Chlamydomonas is a tiny, single-celled green alga found in freshwater environments. It has a simple structure, featuring two whip-like tails called flagella that help it swim. This organism is known for its ability to photosynthesize, using sunlight to produce energy, much like plants do. Its green color comes from chlorophyll, the pigment that captures light. These algae play an important role in ecosystems, serving as a food source for various aquatic organisms. Chlamydomonas is also studied in scientific research for its unique features, including its ability to adapt to different light conditions and its simple genetic makeup, making it a model organism in biology.
