Chlorella has in its body two green color substances: "chlorophyll-a" and "chlorophyll b." It uses photosynthesis, similar to plants which also have chlorophyll. It multiplies rapidly, needing only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.
Many people believe Chlorella can serve as a possible source of food and energy. This is because its photosynthesis process can, in theory, reach 8% efficiency. This is even better than that of other highly efficient crops such as sugar cane, which are already being used for food and energy.
Chlorella reproduce asexually by aplanospores. A single chlorellon cell produces at least 16 non-motile aplanospores and each one of them matures into an individual unicellular alga (chlorellon) under favourable conditions. There are no any reports of sexual reproduction in Chlorella.
