Difference Between Prokaryotic Algae and Eukaryotic Algae

Prokaryotes:

English name：prokaryotes

Composition: is an organism composed of prokaryotic cells that does not have a formed nucleus.

or a class of single cells of mitochondria.

In general, there are several types of prokaryotes: Cyanobacteria.

Bacteria, actinomycetes, spirochetes, mycoplasma.

Wait. Eukaryotes:

English nameeukaryotes

CompositionAn organism made up of eukaryotic cells.

Species range:Including the kingdom Protists, Fungi, Plants, and Animals.

BiologyDefinitions:Eukaryotes are a general term for all organisms that are unicellular or multicellular and whose cells have a nucleus.

It includes all animals, plants, fungi, and other organisms with complex subcellular structures encased by membranes.

Fundamental Difference Between Eukaryotes and Prokaryotes:Eukaryotes have a nucleus inside their cells that are bounded by a nuclear membrane, whereas prokaryotes do not contain a nucleus inside their cells. Hence the eukaryotic name for this type of cell.

Many eukaryotic cells also contain other organelles.

Such as mitochondria, chloroplasts, Golgi apparatus.

Wait. Common prokaryotic algae:Cyanobacteria.

Candida, hair cabbage.

etc., they do not have a nucleus surrounded by a nuclear membrane, so they are prokaryotes.

Common eukaryotic algae:Chlorella, Chlamydomonas, etc., they all have a nucleus surrounded by a nuclear membrane, so they are eukaryotes.

Knowledge Expansion:

Data from molecular biology in the 70s showed that there was an expulsion.

Bacteria other than nuclear organisms as well as eukaryotes, such as:

methanogenic bacteria;

Extremely halophilic bacteria;

Extremely acid-resistant and heat-resistant pyrophylloids;

thermophilic bacterium plastids, etc.

Their 16S rRNA nucleotide sequence is different from both bacteria and eukaryotes. In addition, the cell membranes of these organisms.

The structure, cell wall structure, coenzymes, metabolic pathways, tRNA and rRNA translation mechanisms are all different from those of general bacteria. Therefore, it has been argued that the above-mentioned organisms should be classified as prokaryotes and eukaryotes"Third Biological Realm"or the archaeal kingdom.

Chlorella is eukaryotic.

Chlorella have photosynthetic pigments, and typical green algae cells may or may not be motile. Cells** have vacuoles, pigments are distributed in plastids, and the shape of plastids varies with species. The cell wall is made up of two layers of cellulose and pectin.

Common green algae in activated sludge are chlorella and sponges.

The cells of green algae plants are similar to those of higher plants, with nuclei and chloroplasts, and similar pigments, nutrients, and cell wall components. Chlorophyll a and b are the most pigments, as well as lutein and carotene, so it is green.

Key Value: The economic value of the phylum Chlorella is high. Chlorella are also important in the study of plant evolution; The unicellular Chlamydomonas is thought to be similar to the ancestors of land plants, and the nutrients stored are mainly starches and oils. Among the green algae, such as Ulva, reef membrane, and moss, it has always been an edible seaweed widely harvested by coastal people.

Single-celled green algae such as marine flat algae and chlorella multiply quickly, have high yield, contain a certain amount of protein, sugar, amino acids and a variety of vitamins, and can be used as food, feed or extract protein, fat, chlorophyll and riboflavin and other products. Some green algae can be used as medicine, such as chlorella, Ulva pora, etc. In addition, the algae-fungus symbiosis system and the method of active algae are used to treat domestic sewage and industrial wastewater.

Chlorella is eukaryotic.

There are many types of algae, including cyanobacteria (including Candida, trembling banana, spirulina, hair cabbage, etc.), brown algae (including kelp, wakame, etc.), green algae (including chlamydomonas, water brocade, chlorella, etc.).Among them, cyanobacteria are prokaryotes, and other algae (green algae) are eukaryotes.

Algae are a class of eukaryotes in the protist kingdom (some are also prokaryotes, such as the algae of the phylum Cyanobacteria).

Mainly aquatic, non-vasculating, capable of photosynthesis. They range in size from single-celled dinoflagellates as small as 1 micron long to large brown algae up to 60 meters long. Some leading experts continue to classify algae as plants or plant-like organisms, but algae have no true roots, stems, leaves, and no vascular bundles.

Algae may be composed of one or a few cells, or many cells may aggregate into a tissue-like structure. Filaments can branch or not, and some algae are unicellular, while others aggregate into colonies.

The green algae of the genus Pine algae are formed by the interweaving of numerous branched filaments, and the morphology and function of the filaments are different in different parts. Although predominantly aquatic, algae are ubiquitous, ranging from temperate forests to polar plains. Some varieties live in soil and tolerate long-term water scarcity;Others live in the snow;A few species thrive in hot springs.

The significance of the evolution of prokaryotic and eukaryotic algae lies in their impact on the ecological plum system and their importance in their use and conservation to humans.

Prokaryotic algae are unicellular, relatively simple algae that played an important role in the early marine ecosystems of the Earth and gradually evolved into a variety of different types of bacteria, forming a highly diverse ecosystem base. Eukaryotic algae are complex organisms with the characteristics of prokaryotic algae and other organisms, and they play an important role in modern ecosystems. For example, eukaryotic algae are important organisms in marine, freshwater, and terrestrial ecosystems, and they make important contributions to energy flow and material cycling.

In addition, some species of eukaryotic algae can be used as raw materials for food, cosmetics, medicine, and energy, so they have very high economic value.

The study of evolution contributes to a better or later understanding of the relationships between life and evolutionary paths, to explore the complexity and diversity of ecosystems, and to better understand and use natural resources. For precious algae, humans need to strengthen protection, mitigate climate change, and so on.

Algae without a nucleus are prokaryotes, like cyanobacteria (there are no more common examples), are unicellular algae, macroalgae are not present, and are 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.
