Oedogonium

Oedogonium is a genus of filamentous green algae. Filamentous means the all the cells are in the same plane. Reproduces in 2 ways- sexually and asexually. Reproduces sexually through syngamy.

The anthridia which produces sperm and the oogonium which produces the egg, release the sperm and egg. The egg and sperm then fuse and form a zygote (2n). The zygote then produces the filamentous green algae which is haploid (1n). The oedogonium can also produce asexually through zoospores. These separate from the parent plant through the zoosporangium and continue to divide producing the filamentous green algae. Oedogium is usually freefloating when mature though it can be attached to plants. Lives in quiet, fresh water.
