Rhopalosolen is a genus of green algae in the class Trebouxiophyceae.[1] It is found in freshwater habitats, and is epizoic or epiphytic on various substrates such as rotifers, nematodes, cladocerans, copepods, fungal hyphae, plants, or other algae.[2]
Description
[edit]Rhopalosolen consists of singular cells attached to a substrate. The cells are cylindrical or club-shaped, about 80–430 µm long and 10–45 µm wide when mature,[1] somewhat tapered at the base and broadly rounded at the apex. At the base, the cells are attached to the substrate via a mucilaginous pad. Cells contain a single chloroplast lining the inside of the cell; the chloroplast is initially plate-like but may become dissected with age, and divide into multiple pieces during reproduction. Multiple pyrenoids are present. Adult cells are coenocytic, with multiple nuclei.[3] Species are distinguished from each other based on the size and shape of the cells.[1]
Reproduction occurs asexually and sexually. In asexual reproduction, biflagellate zoospores are produced that escape through a tear in the mother cell wall near the apex.[3] Sexual reproduction has been observed in the type species, R. cylindricus, and is anisogamous.[1]
