Is Chlamydomonas autotrophic or heterotrophic?

Sourav PanApril 26, 2025

Answered

Chlamydomonas species can be either autotrophic or heterotrophic. Most species are obligate phototrophs, relying on light and inorganic carbon sources for growth. Some species, like Chlamydomonas reinhardtii, are facultative heterotrophs and can grow in the dark using organic carbon sources such as acetate. This metabolic flexibility allows them to adapt to varying environmental conditions.
