Sphaerozosma aubertianum is a green algae characterized by its small, spherical cells ranging from 5 to 15 micrometers in diameter. It possesses chloroplasts for photosynthesis and is enclosed by a cellulose-based cell wall for structure and protection. This algae is found in freshwater environments like ponds and lakes, where it plays a role as a primary producer. Reproduction typically occurs through asexual cell division.
