What are the algae of prokaryotes and what are the eukaryotic ones?

Prokaryotic algae include cyanobacteria and prochlorella.

Eukaryotic algae include Cryptophyta, Dinoflagellates, Chrysophyta, Xanthellae, Diatoms, Brown Phytes, Red Phytes, Euglenagi, Chlorophyta, and Rotophyta.

Algae without a nucleus are prokaryotes, like cyanobacteria (there are no more common examples), all are unicellular algae, there are no macroalgae, and they are all individuals that can only be seen under a microscope.

Some unicellular algae and macroalgae are eukaryotes like green algae, red algae, brown algae, common examples like kelp, hair cabbage, nori, etc.

Question 1: Are algae eukaryotes or prokaryotes? Cyanobacteria (including basketball algae, trembling algae, and Candida) are prokaryotes, and other high school organisms are found algae, and in the absence of additional information, we consider them eukaryotes.

Question 2: Which algae are eukaryotes and which are prokaryotes The "cyanobacteria" in algae belong to prokaryotes, such as Candida, hair cabbage, and trembling algae;

Other algae such as black algae, green algae, red algae (such as nori), brown algae (such as kelp) belong to eukaryotes.

Question 3: How can you tell which algae are prokaryotes and which algae are eukaryotes? And how to tell which ones have chloroplasts other than plants, I'm almost confused. Common creatures with algae characters in high school are:

Chlorella: eukaryotes, with chloroplasts;

Chlamydomonas: eukaryotes, with chloroplasts;

Black algae: eukaryotes with chloroplasts;

Chlorella: eukaryotes, with chloroplasts;

Cyanobacteria: Prokaryotes that do not have chloroplasts.

Cyanobacteria belong to the prokaryotic organisms. Cyanobacteria are a group of large single-celled prokaryotes with a long history of evolution and oxygen-producing photosynthesis. Cyanobacteria make the entire earth's atmosphere develop from an anaerobic state to an aerobic state, thus giving birth to the evolution and development of all aerobic organisms.

There are more than 120 species of cyanobacteria with nitrogen fixation ability, especially the aquatic fern Manjianghong, which is symbiotic with the Manjiang red fishy blue bacteria, which is a good green manure. <

Cyanobacteria are prokaryotes without membranous organelles, and their processes in vivo tend to interfere with each other.

Cyanobacteria are unicellular or colonies, or cells arranged in clusters to form algal filamentous filaments, not branched, pseudo-branched or truly branched, without flagella, do not produce swimming cells, and some filamentous species can stretch or swing from side to side;

The cell wall lacks cellulose and is composed of peptidoglycan, often forming a glial sheath outside the wall; There is no true nucleus, the constituent substances of the nucleus are concentrated in the cell**, there is no nuclear membrane and nucleolus;

In addition to chlorophyll and carotenoids, the cells also contain phycocyanin, and some species contain phycoerythrin; The pigments are not contained within the plastid but are scattered at the edge of the cytoplasm, and the algae show different colors depending on the type and amount of pigment they contain.

Prokaryotes are organisms composed of prokaryotic cells, a class of single cells that do not have a forming nucleus or mitochondria, including cyanobacteria, bacteria, actinomycetes, spirochetes, mycoplasma, etc.

Eukaryotic algae: red algae, green algae, rotaphyta, euglena, diatoms, golden algae, dinoflagellates, xanthophytes, brown algae;

Eukaryotic algae are a group of lower autotrophic eukaryotic plants that can perform photosynthesis without roots, stems, and leaves, and appeared about 1.514 billion years ago. Morphology includes single cells, various populations, filaments, phyllodes, tubular bodies, etc. The size ranges from a few microns to a few meters (kelp) and even 100 meters (kelp) The structure is simple and there is no obvious tissue differentiation.

[Cyanobacteria] is a prokaryotic organism, also known as blue-green algae cyanobacteria; Most cyanobacteria have colloidal coatings on the outside of their cell walls, hence the name sliminophytes. Of all the algae organisms, cyanobacteria are the simplest and most primitive one. Cyanobacteria are single-celled organisms that do not have a nucleus.

But photosynthesis can take place. Like bacteria, cyanobacteria belong to the category of "prokaryotes".

Chlorella], also known as Chlorophyta, is a vast majority of eukaryotic organisms with different sizes and morphologies, including unicellular (Chlamydomonas, Drum), groups (Aqua Reticulum spp., Sylvestris spp.), filamentous (Sponge spp.) and tubular (Umbel Spp., Pteridophytes) and so on. Sexual reproduction is common, and its gametes have 2 or 4 caudal flagella. Asexual reproduction includes fission (Protococcus), segmentation, or the production of actospores and aminospores (Filophyta, Sphingalus).

Chlorella are mostly found in freshwater, often attached to submerged rocks and wood, or floating on the surface of stagnant water. There are also species that live in soil and seawater. Planktonic species are the food or oxygen of aquatic animals**. Chlorella are also important in the study of plant evolution; The unicellular Chlamydomonas is thought to be similar to the ancestors of land plants.

Red algae are eukaryotic organisms, and the plant body is mostly filamentous, phyllodis, or dendriform, and a few are single-celled or colonies. Rhodophyta algae, about 3,000 species. Algae body purple red, rose red, dark red and other colors.

Most of the red algae grow in the ocean, widely distributed, many species, according to statistics, there are more than 3,700 species, many of which have important economic value. In addition to food, it is also a raw material for medicine, textile, food and other industries.

Brown algae] A member of the phylum Phaeophyta, a group of higher algae, belonging to eukaryotes. There are about 1,500 species, distributed in cold-water bodies along the coast of the continent, and freshwater species are rare. Its color depends on the ratio of brown pigment (Fucus flavonin) to green pigment (chlorophyll), ranging from dark brown to olive green.

The inflated air sac causes the photosynthetic portion of the phyllodes to float at or near the water surface. Once the main source of iodine and potassium, algae is still important in algin, a gel used as a stabiliser in food baking and ice cream manufacturing.

Algae] The order of Algae of the phylum Chlorophyta, which is eukaryotic. The algae are spherical in shape and about 5 mm in diameter. Algae has a thin colloidal layer on the outside and can swim.

Each algae is formed by 1,000-50,000 Chlamydomonas cells arranged in a single layer on the surface of the sphere. Vegetative cells have the ability to photosynthesize and can produce organic matter, and there are many of them. Each cell has a cup-shaped chloroplast, the base of the chloroplast has a nucleus, the front end of the cell is facing outward, and there are two flagella of equal length.

Because the glial membrane on the outside of each cell is squeezed, the cells appear polygonal when viewed from the surface.

Most of the words are eukaryotic, just remember that cyanobacteria are prokaryotes
