Note the distinctive apical rings that
form from successive cellular divisions.
• Oedogonium is a form of filamentous green algae. It is capabable of reproducing asexually, which means that each oedogonium has both male and female reproductive organs. In asexual reproduction, the oedogonium fragments and produces zoospores. Zoospores are able to move spontaneously through the water. Once the zoospore is produced, it is released and is free to find a viable substrate. Once found, the zoospore's cells are able to divide and form a new filament of oedogonium.
