Strombomonas gibberosa is a freshwater eukaryotic organism with an ovoid or pear-shaped cell structure that often appears swollen or gibbous. It is enveloped by a flexible pellicle and propelled by two unequal flagella: a long, trailing posterior flagellum and a short anterior flagellum. These flagella enable movement through its aquatic habitat. Within its cell, Strombomonas gibberosa contains chloroplasts that are typically discoid or cup-shaped, facilitating photosynthesis. An eyespot near the base of the shorter flagellum aids in light perception. Reproduction occurs primarily through asexual binary fission. This species is commonly found in freshwater environments such as lakes and ponds, playing a role in nutrient cycling and contributing to the ecosystem through its photosynthetic activities.
