What are the ways of reproduction of Chlamydomonas?

Chlamydomonas reproduces sexually and asexually.

It reproduces asexually in favorable conditions (in warm weather) by dividing in half.

4 cells are formed, which grow and transform into an independent adult organism.

Chlamydomonas reproduces sexually under unfavorable conditions (low temperature). It sheds flagella, nucleus division begins, and a large number of gametes with flagella are formed. Gametes go out into the water, connect in pairs, forming a zygote. It is covered with a dense shell, hibernates at the bottom of the reservoir. Under favorable conditions, it begins to divide, forming 4 cells, which turn into an independent organism.
