Brad Burcz Gonium Classification Empire  Eukaryota  Kingdom  Plantae  Subkingdom  Viridaeplantae  Phylum  Chlorophyta  Class  Chlorophyceae  Order  Volvocales  Family  Goniaceae  Genus  Gonium Gonium are small, ovoid or angular shaped, motile, freshwater alga, around 10 micrometers in size. Gonium are biflagellate, and use their two flagella to swim through their environment. The cells contain a very large cup shaped chloroplast, with at least one pyrenoid, where carbon dioxide fixation takes place. Each cell also contains an eye spot and has two contractile vacuoles near the base of the flagella. They are very similar to Chlamydomonas . Gonium species are colonial, with each cell enclosed in a gelatinous, mucilage, sheath. The sheaths can join together, forming colonies of 4, 8, 16, or 32; colonies are arranged in a flat layer and are oriented in the same direction, although when cultured, individual cells may be solitary, instead of forming colonies.

Unformatted text preview: Being a chlorophyte, Gonium utilizes photosynthesis to make sugar, used in its metabolism. The Genus Gonium represents 16 species. Gonium pectorale is one of the most abundant and encountered species of green algae. Of all the species studied, three of them have known carbon sources. Growth has been supported by acetate, pyruvate, and DL-lactate. Reproduction can be sexual (isogamous), where cells of the same size and of different mating types, "+" and "-" fuse together and form a zygote, producing four cells. Asexual reproduction by autocolony formation, may also take place, wherein a cell has repeated mitotic nuclear division, resulting in a multinucleated cell, with cytokinesis occurring for each nucleus. Cells in Gonium colonies are identical and have shown no evidence of specialization....
