How does Chlamydomonas reproduce? Asexual and sexual reproduction methods

Chlamydomonas reproduction method

Chlamydomonas does not bloom and bear fruit like terrestrial plants and has branches and leaves. It cannot be propagated by sowing, cuttings, division, or leaf cuttings. It has two types of reproduction methods: asexual and sexual. Generally speaking, it can reproduce at any time, but it reproduces faster in the warm environment of spring and autumn.

Common reproduction methods of Chlamydomonas

1. Asexual reproduction of Chlamydomonas

Chlamydomonas can reproduce asexually in a suitable environment. During asexual reproduction, the cells often remain motionless, the flagella will slowly fall off, and the protoplasm inside will undergo several mitosis to form 2, 4, 8 or 16 daughter protoplasts, which then form zoospores. The spores will then be released, drift in the water, and each grow into a new individual.

2. Sexual reproduction of Chlamydomonas

When Chlamydomonas reproduces sexually, it also sheds its flagella first. After several divisions, the protoplasm will produce cells with flagella, called gametes. They are smaller than zoospores. After the gametes are released, they combine in pairs to produce zygotes. The zygotes secrete thick walls, germinate in a suitable environment, and form an individual.
