At least 325 species of unicellular green algae belong to the genus Chlamydomonas. These are frequently discovered in freshwater, saltwater, stagnant water, and even moist soil.
The thallus is represented by a single cell in the Chlamydomonas structure.
Thallus can have a pyriform, round, rectangular, oblong, or ellipsoidal shape.
The usual thalli are pyriform or pear-shaped, with a narrow anterior end and a wide posterior end.
A thin and sturdy cellulose cell wall surrounds the cell.
The cytoplasm is located between the chloroplast and the cell membrane.
The chloroplast cavity, which resembles a cup, contains the cell's enormous, dark nucleus.
The cell's anterior portion has two flagella, which aid in movement. At the base of each flagellum are two contractile vacuoles.
On the front edge of the chloroplast, there is a little red eyespot.
