is green algae prokaryotic or eukaryotic

The prokaryotic cells consist of bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms). @anon20136, Archaebacteria is the bacteria that lives only in extreme environments, like in nuclear plants, and the dead sea. In general, prokaryotic cells are those that do not have a membrane-bound nucleus. -Includes plants and some multicellular algae -Eukaryotic-Multicellular-Have cell walls ... Algae, eukaryotes. Microscopic algae (microalgae) can be identified, as well as large seaweeds (macroalgae). Nuclear membrane is absent and DNA is not associated with histone proteins. In prokaryotic cells 70s type of ribosomes are present in the cytoplasm. Prokaryotic cells lack membrane-bounded organelles (plastids, mitochondria, nuclei, Golgi bodies, and flagella) and occur in the cyanobacteria. Algae are eukaryotic photosynthetic thallophytes lacking archegonia. B. Most eukaryotic cells are multicellular. ... Green algae (chlorophytes and charophyceans) are named for their grass-green chloroplasts. Figure 3: Algae. Bacteria are an example of prokaryotes. Besides bacteria, the cyanobacteria (blue-green algae) are a major group of prokaryotes. The terms prokaryotic and eukaryotic were suggested by Hans Ris in the 1960’s. Figure 3. That would include plant, animal, algae, and fungal cells. Join now. This leads to the question of the possibility of a cell containing an endosymbiont to itself become engulfed, resulting in a secondary endosymbiosis. Eukaryobc cells are the cells in which true nucleus is present. Prokaryotic cellsEukaryotic cellsCells which do not have any nuclear membrane are called prokaryotic cellsCells which have nuclear membrane are called Eukaryotic cellsOrganisms having such cells are called ProkaryotesExampleBacteria,Blue green algae are Prokaryotes and their cells are called Prokary The terms prokaryotic and eukaryotic were suggested by Hans Ris in the 1960’s. 3. It occurs in all living organisms except bacteria and blue green algae. Prokaryotes are unicellular organisms that don’t have a membrane-bound nucleus and other organelles. Nucleus and other membrane bound organelles are present only in eukaryotic cells and not in prokaryotic cells. The eukaryotic cells are found in all multicellular animals, plants and fungi. The size dependency of maximum growth rates was investigated in cyanobacteria and in green algae (Chlorophyta). Prokaryotic vs Eukaryotic Cells Major Cell Types Prokaryotic. Microscopic algae (microalgae), as well as large sea-weeds (macroalgae), can be identified. Eukaryotes Cells are divided into one of two major classifications, eukaryotic or prokaryotic. Middle School. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. 1. Which of the following is no available in animal cells? They are prokaryotic and eukaryotic. 1. Prokaryotic Algae: The blue-green algae (Cyanophyceae or Cyanophycophyta) are prokaryotic algae. In these algae, their nuclear materials, deoxyribo-nucleic acid (DNA), is not delimited from the remainder of the protoplasm by a nuclear membrane, but rather it is dispersed to some degree throughout the cell. - Nucleus present. Synonyms: procaryotic; prokaryotic. Besides bacteria, the cyanobacteria (blue-green algae) are a major group of prokaryotes. True. Although most of the taxonomic groups of algae include multicellular macroscopic organisms, there are also unicellular forms in majority of such groups. Acad. All living organisms fall into one of two categories: Eukaryotes (plants, animals, and fungi) or Prokaryotes (bacteria and archaea). Eukaryotic Cell. Like the green algae, the red algae are an ancient group in the fossil record, and some of the oldest fossils interpreted as being of eukaryotic origin are often referred to the red algae, although clearly these organisms were very different from any extant alga. prokaryotes are the cyanobacteria or blue-green algae. Progress. Explanation: Prokaryotes are organisms whose cells do not contain a distinct nucleus, bounded by a nuclear envelope, in contrast to eukaryotic organisms that do have distinct nuclei.Prokaryotes include both the bacteria and the archaea, which appear to be only … Eukaryotic cells are those that have a true nucleus. As a result of these features, prokaryotic entities — cyanobacteria (also known as blue-green algae) and eukaryotic organisms (all other algal species) are generalised as “algae.” Because ” algae ” do not constitute a natural unit that has descended from a common ancestor, like cyanobacteria, is popular in the informal” algae “community,” said Linda Graham, a botany professor. The structure of a eukaryote (a typical plant cell) is shown in Figure 10.2a. Which part of the cell containing hydrolytic enzyme? MEMORY METER. Key Terms. Prokaryotic Algae: The blue-green algae (Cyanophyceae or Cyanophycophyta) are prokaryotic algae. This indicates how strong in your memory this concept is. The name “algae” is misleading because it suggests a relationship to the eukaryotic algae, and many scientists prefer the alternative name “cyanobacteria” rather than “blue-green algae.” These were the organisms responsible for producing oxygen initially released into the atmosphere. Bacteria and blue-green algae are both primitive prokaryotes that live on earth now, as well as long time ago. Definition. Prokaryotic cells are cells in which true nucleus is absent. Easy. An organized nucleus is present. They do not have a definite nucleus which includes bacteria and cyanobacteria (blue-green algae). Prokaryotic cell Prokaryotic cells are cells in which true nucleus is absent. - Simpler, much smaller than eukaryotic cells. The cheek cells that you looked at last week, and cells of every other organism except bacteria are eukaryotic.Only bacteria and cyanobacteria (also called blue-green algae) have prokaryotic cells.Prokaryotic cells differ from eukaryotic cells in that they lack a membrane- bound … These are similar in ultrastructure and pigment composition to those of plants. Like green plants, they depend on sunlight to make their food. Something went wrong. In eukaryotes, DNA is located within the nucleus; whereas, prokaryotes lack a nucleus. In eukaryotic algae, sexual reproduction occurs through the union of gametes. PROKARYOTIC EUKARYOTIC ; Prokaryotic cells do not consist of cell membrane: Eukaryotic cells consist of cell membrane: Genetic material is present in cytoplasm: Genetic material is present in nucleus: Eg. There are two basic types of cells in the algae, prokaryotic and eukaryotic. When Onion cell, cheek cell Scientists speculate that, in a process called endosymbiosis, an ancestral prokaryote engulfed a photosynthetic cyanobacterium that … Cell …. Similarities between nucleoid area (prokaryotic) and nucleus (eukaryotic) are: Genetic material (DNA) is found in both the nucleoid are of prokaryotes and the nucleus of eukaryotes. 2. Chlorophyll A & B 2. Eukaryotic promoters are much larger and more complex than prokaryotic promoters, but both have a TATA box. The prokaryotes consists of the bacteria and blue green algae and were first to arise in biological evolution (i.e., about 3 x 10 9 years old). www.differencebetween.net/science/...between-cyanobacteria-and- Green algae are a group of photosynthetic, eukaryotic organisms that include species with haplobiontic and diplobiontic life cycles. Vind stockafbeeldingen in HD voor Green Algae Chlorophytaincluding Prokaryotic Eukaryotic Forms en miljoenen andere rechtenvrije stockfoto's, illustraties en vectoren in de Shutterstock-collectie. In haplobiontic species only the haploid generation, the gametophyte is multicellular. Algae are eukaryotic organisms, which are organisms whose cells contain a nucleus and other structures (organelles) enclosed within membranes. For example, in blue-green algae and bacteria, there is no definite nucleus. Preview. The oldest reliable date for the appearance of the eukaryotes is about 1.9 billion years ago, when the first members of a group of unicellular organisms called acritarchs appear in the fossil record in China. Among prokaryotes, bacteria are the most common and multiply very fast. Estimated7 minsto complete. ... (blue-green algae). Life began about 3.5 billion years ago in the oceans with the appearance of prokaryotes.

Category: pets fish and aquariums. (b) Assertion (A) and Reason (R) both are true but reason B is not a correct explanation of the assertion (A) As mentioned above, algae are eukaryotic organisms. Starch as the Food Reserve 3. The genetic material of the cell (the DNA) may be enclosed (entirely covered) in a nuclear membrane … For example, in blue-green algae and bacteria, there is no definite nucleus. Cyanobacteria: most complex eukaryotic cells and formerly known as blue-green algae. Prokaryotic DNA is in the cell’s central part: the nucleoid (). Anonymous. Thousands of new, high-quality pictures added every day. Sci. Bacteria and algae are prokaryotic cells. Size of the cell is generally large (50- 100 µm). Microalgae are a broad category of photosynthetic microorganisms that comprise the eukaryotic microalgae and the prokaryotic cyanobacteria, also known as blue-green algae. A group of microtubules that helps with cell division after mitosis in specific algae. These eukaryotic organisms have a nucleus that is enclosed within a membrane. 4. Cyanobacteria or blue-green algae are a type of microalgae which does not belong to eukaryotic algae. Comparing Prokaryotic and Eukaryotic Cells: An Overview (chapter 4) Prokaryote • One circular chromosome, not in a membrane • No histones • No organelles • Bacteria: peptidoglycan cell walls • Archaea: pseudomurein cell walls • Divides by binary fission Eukaryote The chimera of Greek mythology was part goat, part lion, and part serpent. Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. Eukaryotic Cell. Examples: The prokaryotic cells in blue-green algae and bacteria. 2. Accordingly, what is the difference between eukaryotic and prokaryotic cell membrane? Practice. Amoeba cell, Human cheek cell, onion peel cell - Eukaryotic Blue-green algae cell, Bacterium cell - Prokaryotic. The DNA of prokaryotic cells is not contained within a nucleus. Prokaryotic cells lack both, a well-defined nucleus and membrane-bound cell organelles. What is the name of fluid part of the cytoplasm of the Eukaryotic cells ? The chloroplasts of red and green algae exhibit DNA sequences that are closely related to photosynthetic cyanobacteria, suggesting that red and green algae are direct descendants of this endosymbiotic event. Eukaryotes: Fungi, Algae, Protozoa 12 © 2016 Pearson Education, Ltd. Rotifer, probably the bdelloid Philodina. Eukaryotic cells contain membrane-bound organelles, including a nucleus. Algae is a collective term for many organisms, so it is classified into different kingdoms. Eukaryotic cells are those that have a true nucleus. cyanobacteria: photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae; aerobic: living or occurring only in the presence of oxygen; endomembrane: all the membraneous components inside a eukaryotic cell, including the nuclear envelope, endoplastic reticulum, and Golgi apparatus MCQ on Eukaryotic Cells. 2. 2) and, second, in the newly evolved eukaryotic algal lineages originating from either primary (green and red algae) or secondary endosymbiosis (brown algae). Eumycota-Fungi-Decomposers-hairy filamentous molds. Upvote (2) Was this answer helpful? However, prokaryotes differ from eukaryotic cells in several ways. Bacteria, and this includes cyanobacteria, often referred to as blue-green algae are all prokaryotes. Prokaryotic cells are simpler while eukaryotic cells are more complex. Thus, two types of cells are found in the organisms: eukaryotic and prokaryotic depending on whether cells contain membrane-bound organelles or not. Bacteria are an example of prokaryotes. PROKARYOTIC ... • This is the reason why cyanobacteria, like green algae, can exploit deeper waters where the quality and quantity of illumination is inappropriate for the photosynthetic plants. Where do Eubacteria live? Prokaryotes are always unicellular organisms. A … Eukaryotic cells are generally bigger — up to 10 times bigger, on average, than prokaryotes. According to the morphological point of view, prokaryotic cells are the most primitive cells. The prokaryotes consist of bacteria and blue green algae.

Cells which have organized nucleus are known as eukaryotic cells. These seem curious decisions. These cells originated approximately 3.5 billion years ago, which was about 1 billion years after Earth’s formation, and were the only life forms on the planet until eukaryotic cells emerged approximately 2.1 billion years ago. Bacteria are prokaryotic cells; fungi, protozoa, algae, plants, and animals are composed of eukaryotic cells. The eukaryotic cells are found in all multicellular animals, plants and fungi. - Found in all other organisms, plants and animals. Bacteria, the oldest form of life on Earth, are prokaryotes. CYANOBACTERIA (blue-green algae) •Prokaryotic; lack the organized chloroplasts of eukaryotes; their photosynthetic apparatus distributed peripherally in cytoplasm. The chromatin bodies remain scattered inside the … So most virologists consider viruses non-living. Sexual reproduction typically comprises of meiosis using genetic material from two different parent cells. (a) Red algae and (b) green algae (seen here by light microscopy) share similar DNA sequences with photosynthetic cyanobacteria. Scientists speculate that, in a process called endosymbiosis, an ancestral prokaryote engulfed a photosynthetic cyanobacterium that evolved into modern-day chloroplasts. Jack0m/Getty Images. (a) Red algae and (b) green algae (visualized by light microscopy) share similar DNA sequences with photosynthetic cyanobacteria. The algae part of the common name can be a little misleading since most algae are considered plants, which are classified as Significant allometric relationships were found between size and maximum growth rate for both cyanobacteria and green algae. In fact 'pro-karyotic' is Greek for 'before nucleus'. Some protists have organelles that are found in animal cells ( mitochondria ), while others have organelles that are found in plant cells ( chloroplasts ). The chloroplasts of red and green algae, for instance, are derived from the engulfment of a photosynthetic cyanobacterium by an ancestral prokaryote. It has chloroplasts for photosynthesis because it is a plant. Oscillatoria, genus of blue-green algae common in freshwater environments, including hot springs.

They can replicate only inside a … The eukaryotic cell is a chimera of prokaryotic ancestors. Has cross walls. Prokaryotic cells differ from eukaryotic cells in that they lack a membrane- bound nucleus and organelles. So, the correct answer is 'False'. While most algae are eukaryotic, cyanobacteria are the only exception. In eukaryotic algae, sexual reproduction occurs through the union of gametes. (a) Red algae and (b) green algae (seen here by light microscopy) share similar DNA sequences with photosynthetic cyanobacteria. Prokaryotic Cell: The structure of a eukaryote (a typical plant cell) is shown in Figure 10.2a. They use photosynthesis to gain energy. An organized nucleus is absent. It is the presence of a nucleus Usually, spirogyra algae are seen as floating slimy masses, during summer. They appear to have originated in freshwater or a terrestrial environment. Eukaryotic algae are sexually dimorphic; Therefore, male and female gametes are produced by different individuals. In some green algae, cytokinesis occurs by a phycoplast. Is green algae prokaryotic or eukaryotic? All types of blue green algae and bacteria are included in this kingdom. Scientists speculate that, in a process called endosymbiosis, an ancestral prokaryote engulfed a photosynthetic cyanobacterium that evolved into modern-day chloroplasts. Early work on photosynthetic eukaryotes led to the identification of two fundamentally different types of plastid. Eukaryotic Cells. Algae. (A) Blue green algae is a prokaryotic cell: (R) In prokaryotic cell,cell division occur very fast. algae + eukaryotic cells (origin (alveolates (dinoflagellates, ciliates),…: algae + eukaryotic cells, green algae, embryophytes, eukaryotes, prokaryotes, green algae 1. The prokaryotes consists of the bacteria and blue green algae and were first to arise in biological evolution (i.e., about 3 x 10 9 years old). In prokaryotic cells, ribosomes are smaller and cell organelles are not surrounded by double membranes. True. Cells which have organized nucleus are known as eukaryotic cells. The division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus. Why are blue-green algae prokaryotic while green, brown, and red algae are eukaryotic? For example, in the mouse thymidine kinase gene, the TATA box is located at approximately -30 relative to the initiation (+1) site (). Nucleoid region: it is an irregularly shaped region that serves its genetic material. 1, Table I) are not significantly different when tested by analysis of covariance (P > 0.05), so eukaryotic green algae and prokaryotic cyanobacteria apparently follow the same allometric relationship between size and … This group consists of single-celled prokaryotes — organisms without a … Common name - yogurt bacterium. Though they are capable of conducting oxygen-producing photosynthesis and live in many of the same environments as Cell Walls with Cellulose 4. 2. The cheek cells that you looked at last week, and cells of every other organism except bacteria are eukaryotic. Blue-green algae, also called cyanobacteria, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. 1. Blue-green cyanobacteria or algae are a type of microalgae that do not belong to eukaryotic algae. This evidence suggests the possibility that an ancestral cell (already containing a photosynthetic endosymbiont) was engulfed by another eukaryote cell, resulting in a secondary endosymbiosis. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. The oldest reliable date for the appearance of the eukaryotes is about 1.9 billion years ago, when the first members of a group of unicellular organisms called acritarchs appear in the fossil record in China. 1. That would include plant, animal, algae, and fungal cells. For example, archaebacteria, bacteria, blue green algae are all prokaryotes. structure of prokaryotes. The remainder of the algae are eukaryotic and have organelles. As you can see, to the left, eukaryotic cells are typically larger than prokaryotic cells. Are Cyanobacteria prokaryotic or eukaryotic? - Larger than prokaryotic cells, compartmentalized by organelles. Discusses the major differences between prokaryotic and eukaryotic cells. ), the red algae have been left to part 2/2, whereas the prokaryotic ‘blue-green algae’ have been put in part 1/1, together with a motley collection of eukaryotic groups traditionally classified as ‘fungi’. Green algae are eukaryotes characterized by chlorophylls a and b as the major photosynthetic pigments (but colorless, heterotrophic taxa are also present [e.g., Polytoma, Polytomella, and Hyalogonium]), starch (α-1,4 and α-1,6 polymer of glucose) located within the chloroplast as the major storage product, and flagella of the whiplash (smooth) type (e.g., Bold and Wynne, 1985). That would include plant, animal, algae, and fungal cells. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Cyanobacteria are sometimes considered algae , but they are actually bacteria ( prokaryotic ), where the term " algae " is now reserved for eukaryotic organisms. They are primitive and incomplete cells. Instead, prokaryotic chromosomes are found in a localized area of the cell called the nucleoid region. The fossil record and genetic evidence suggest that prokaryotic cells were the first organisms on Earth. by December 10, 2020. Correct option is . Cytoplasm does not have ER and other membranous structures (except chromatophores in photosynthetic bacteria and blue-green algae). E. coli has around 1.6mm, or 4 million base pairs, of DNA—compare this to the 2m of DNA inside each human cell. Only bacteria and cyanobacteria (also called blue-green algae) have prokaryotic cells. USA99:15554-15559. 2.

Today, the only prokaryotes we know of are bacteria (like the bacteria that give you strep throat and the bacteria in our digestive systems that help us to digest our food) and cyanobacteria (blue-green algae). 2. Here we’re going to discuss about Prokaryotic cells and Eukaryotic cells. 2 differences: Eukaryotic cells have a true nucleus, prokaryotes don't. (a) Assertion (A) and Reason (R) both are true and reason (B) is correct explanation of the assertion A. The fertilized egg cell, the diploid zygote, undergoes meiosis Cyanobacteria are prokaryotic often referred to as ‘blue - green algae’. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. ALGAE AND THE ORIGIN OF EUKARYOTIC CELLS Life began about 3.5 billion years ago in the oceans with the appearance of prokaryotes. - Typical of bacteria and blue-green algae. The feedback you provide will help us show you more relevant content in the future. Algae, along with plants, animals, protozoa and fungi, are all eukaryotes.

The eukaryotic cells are found in all multicellular animals , plants and fungi. Log in. Well, not quite all of them because, for some reason (page limits? Eukaryotic cells contain membrane-bound organelles, including a nucleus. After about 2 billion years, aggregates of prokaryotic cells evolved into eukaryotic cells. 04. Eukaryotic Cell Cell Division by Cell Plate Formation Rather than Furrowing (some Green Algae) Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches , and were at one time treated as algae, hence the common name of blue-green algae. is algae prokaryotic or eukaryotic. A Blue green algae are too small to see without the use of a microscope. Blue green algae or cyanobacteria are still considered as prokaryotes. Asexual reproduction of algae includes the production of mobile spores and division by mitosis. In these algae, their nuclear materials, deoxyribo-nucleic acid (DNA), is not delimited from the remainder of the protoplasm by a nuclear membrane, but rather it is dispersed to some degree throughout the cell. Derivation: prokaryote (a unicellular organism having cells lacking membrane-bound … Prokaryotes are single-celled organisms that lack a membrane-bound nucleus and usually lack membrane-bound organelles (mitochondria, chloroplasts; see cell, in biology). 4.7/5 (627 Views . For example, archaebacteria, bacteria, blue green algae are all prokaryotes. Ans. Log in. Prokaryotic cells are found in bacteria, including both Archaebacteria and Eubacteria, and including the blue-green algae. A. 'blue'), giving them their other name, "blue-green algae", though modern botanists restrict the term algae to eukaryotes and do not apply it to cyanobacteria, which are prokaryotes. Desiccation tolerance must have evolved at least two times independently, first, in the prokaryotic algae (=cyanobacteria, Chap. In eukaryotic green algae, thylakoid membranes are housed within a cellular organelle known as the chloroplast; in prokaryotic cyanobacteria, thylakoids are found in the cytoplasm as an intracellular membrane system (see Fig. Bacterial cells are examples of prokaryotes but algae are eukaryotes. Algae. These are unicellular, eukaryotic organisms with a well-defined nucleus enclosed in a nuclear membrane. As you can see, to the left, eukaryotic cells are typically larger than prokaryotic cells. Today in lab, we will look at examples of both prokaryotic and eukaryotic unicellular organisms that are commonly found in pond water. Biology. 2. These seem curious decisions. The number of microalgal species is not completely known, but some studies have referred that it may be comprised between 200,000 and some millions of microalgal species ( Norton et al., 1996 ). Like mitochondria, plastids also contain circular genomes and divide by a process reminiscent of prokaryotic cell division. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. cyanobacteria: photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae; aerobic: living or occurring only in the presence of oxygen; endomembrane: all the membraneous components inside a eukaryotic cell, including the nuclear envelope, endoplastic reticulum, and Golgi apparatus That is what justifies their inclusion among microorganisms. The cells of Bacteria and Cyano Bacteria (blue green algae) lack a well organised nucleus and are called prokaryotic cells. Septate. ALGAE AND THE ORIGIN OF EUKARYOTIC CELLS. Eukaryotic Cell vs. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not.Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. In other words, prokaryotic cells don't have a lot to them, and eukaryotic cells have lots of different parts with different functions. A). They do not have a definite nucleus which includes bacteria and cyanobacteria (blue-green algae). Aredalga waschosensinceit is the chloroplasts ofthis eukaryotic group that most obviously resemble an existing line of prokaryotes, the blue-green algae (3, 4, 7, 8). A. Green algae are a group of photosynthetic, eukaryotic organisms that include species with haplobiontic and diplobiontic life cycles. Bacteria are examples of the prokaryotic cell type. Key Terms. Some have characteristics of animals (protozoa), while others resemble plants (algae) or fungi (slime molds). Difference # Prokaryotic Cells: 1. Practice Prokaryotic and Eukaryotic Cells. Keeping this in view, is mouth smear prokaryotic or eukaryotic? Diatoms are a type of plankton called phytoplankton, the most common of the plankton types. The diplobiontic species, such as Ulva, follow a reproductive cycle called alternation of generations in which two multicellular forms, haploid and diploid, alternate, and these may or may not be isomorphic (having the same morphology). Several clades exist that still have some extant members whose plastids have numerous prokaryotic characters. The chloroplasts of red and green algae, for instance, are derived from the engulfment of a photosynthetic cyanobacterium by an ancestral prokaryote. [Nostoc; Porphydium cruentum]}, author = {Gantt, E and Lipschultz, C A and Cunningham, Jr, F X and Mimuro, M}, abstractNote = {Energy flow between the extrinsic phycobilisomes and the photosystems within thylakoids, is probably mediated by a blue anchor polypeptide. Early work on photosynthetic eukaryotes led to the identification of two fundamentally different types of plastid. The chloroplasts of red and green algae, for instance, are derived from the engulfment of a photosynthetic cyanobacterium by an early prokaryote. Prokaryotic and Eukaryotic Algal cell structure 1. alga). Join now. Nuclear membrane is absent and DNA is not associated with histone proteins. They are prokaryotic and eukaryotic.
