C. moewusii is typically a freshwater species and occupies a significant position as a model organism for various scientific studies due to its relatively simple cellular structure and ease of cultivation.

As in other Chlamydomonas species, reproduction in C. moewusii occurs both asexually through cell division and sexually through the formation of gametes.

[3] Chlamydomonas moewusii is a heterothallic species, exhibiting distinct behavioral differences between the gametes of its two mating types.

Throughout this motile phase, there is no fusion of nuclei or cytoplasm between the cells; instead, they remain connected at their anterior ends by a short protoplasmic bridge, moving consistently in one direction.

This motility is essential for various biological processes, including navigation towards light sources for photosynthesis, finding optimal environmental conditions, and locating nutrients.The motion of C. moewusii is primarily characterized by a type of swimming known as "flagellar beating."
