Can algae carry out photosynthesis?

Algae plants can generally carry out photosynthesis, but a few can't. For example, in the deep sea, there is an algae that can live for hundreds of years without photosynthesis, and can directly absorb nutrients from the surrounding seawater without photosynthesis. Algae plants generally have pigments for photosynthesis, which can use light energy to synthesize inorganic substances into organic substances; For its own needs, it is an autotrophic native plant that can live alone.

Algae Algae is a primitive and ancient lower organism. Algae have simple structure, no differentiation of roots, stems and leaves, and most of them are single cells, colonies or multicellular phyllodes. For example, Chlorella is a single cell, Volvariella volvacea belongs to a group, and kelp is a thallus. Algae contain photosynthetic pigments such as chlorophyll, which can carry out photosynthesis and belong to autotrophs.

From a historical point of view, the first record of "algae" in the history of China was in the Book of Songs, a collection of poems in the Spring and Autumn Period and the Warring States Period. The Book of Songs Guofeng Picking Apples records: "In order to pick algae? On another line "; The Book of Songs Truffle Flooding records: "Take algae thin" and so on.
