One of the interesting volvox characteristics is that the special cells formed around the equator during asexual reproduction develop into germ cells. Volvox carteri F. Stein 1878 is a species of colonial green algae in the order Volvocales. Cytoplasmic strands formed during cell division connects adjacent cells, Polarity exists in the coenobium as cells of the anterior region have bigger eyespots than cells of the posterior region, Eyespot is used for light reception, cells with larger eyespot are grouped together, and they facilitate phototaxis movement, Volvox significantly contribute to the production of oxygen and also many aquatic organisms feed on them, Volvox show cell differentiation in terms of reproductive and somatic cells, Most of the species reproduce by both mechanism, asexual under the favourable condition and sexual reproduction during the unfavourable condition, The gonidium undergoes multiple division to form a colony of around 3200 cells, Each coenobia may be monoecious or dioecious, Biflagellated antherozoids are released either in a group or individually, Antherozoids get attracted towards oogonium by the, Out of many sperms that enter, only one antherozoid fertilises the egg, Ova and spermatozoa undergo fertilization to form a, Zygote forms cyst and becomes red due to the accumulation of hematochrome, The zygote detaches from the parent after the disintegration of the parent and remains dormant for a longer duration. The coordinated movement of flagella enables the colony to move in the water. Volvox Video #1 https://www.carolina.com/algae/volvox-aureus-living/152655.pr Darkfield light micrograph.
