What are algae called? Why are algae all autotrophic?

Algae are autotrophic lower plants that have photosynthetic pigments and can live independently. Most of the algae cells have chloroplasts, chloroplasts contain chlorophyll a, some algae also contain chlorophyll b, c, various carotenes such as , or carotene, lutein, etc.; In addition, red algae contain phycocyanin and phycoerythrin (both are collectively called phycobilin), which are similar to cyanobacteria. In the presence of light, algae use these photosynthetic pigments for photosynthesis, using light energy, absorbing carbon dioxide to synthesize cellular matter while releasing oxygen.

Therefore, algae are generally inorganic nutrients.

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. This is the same as bryophytes.

What are the algae plants.

Algae are primitive and ancient lower plants. This type of plant is characterized by a simple structure, and organs such as roots, stems, leaves, flowers, and fruits are not differentiated, but they contain chlorophyll, so they can carry out photosynthesis. Common algae include kelp, red algae, dinoflagellates, yellow algae, diatoms, cyanozoa, green algae, brown algae, golden algae, conch, hijiki, euglena, wakame, etc.

Jackie. The genus Hylan is a plant of the phylum Rhodophyta, about 5-12cm tall. The plants are clustered, with thin stems and cylindrical branches, mostly growing on rocks in the intertidal zone.

The current location of Murphyta, Chlorella is a plant of the phylum Chlorophyta. Its cells are very similar to those of higher plants. They all have nuclei and are mostly found on the surface of fresh or stagnant water with a large chlorophyll content.

Green algae. Golden algae is a type of plant of isoflagellates that is golden-brown in color overall. It is a single-celled swimming variety. This plant contains carotene and natural pigments and prefers to live in water with low temperatures and little organic matter.

Golden algae. Diatoms are a plant of the phylum Diatoms. Its shapes are chain-like, ribbon-like, cluster-like, etc. The whole plant is orange-yellow, and the vegetative body is flagellated. They mostly grow in the open waters of the ocean.

Diatom. Wakame is an algae plant of the phylum Brown Algae. The whole plant is brown and tough. The plant is 1-2m long, with a distinct protrusion in the middle and pinnate lobes on both sides. It grows mainly in areas 1-4 meters below the low tide line.
