Chlamydomonas zoospores are haploid flagellated cells. As long as conditions are favorable, these cells reproduce asexually. As many as sixteen cells may form by mitosis within a parent cell. Daughter cells escape when the cell wall ruptures. When conditions become less favorable, the asexually produced cells develop into gametes. There are two different mating types. When gametes of different mating types meet, they first undergo cytoplasmic, then nuclear, fusion. The product of this sexual reproduction is a diploid zygote. The zygote loses its flagella and develops a thick wall that enables it to survive adverse conditions. When the zygote germinates and undergoes meiosis, it produces four haploid zoospores. They reproduce asexually until conditions change once again.
