Give examples of unicellular plants.

The class of algae belongs to unicellular plants. Such plants of various species may have special features. Despite the fact that their body consists of only one cell, they have characteristic features. For example, one of the more popular examples of unicellular plants is Chlamydomonas. Its main features are: 1) a light-sensitive eye (with its help they determine where the greatest amount of sunlight is located for the photosynthesis process), 2) the presence of a chromatophore (instead of numerous chloroplasts), 3) there are contractile vacuoles (they act as a pump that pumps out excess water ).
In addition to chlamydomonas, unicellular plants also include: chlorella, pleurococci, diatoms.
