Biking to the Commons. Directly across Rich Street from Columbus Commons is a CoGo Bike Share station, providing a great alternative mode of transportation to and from the Commons. And if you'd like to ride your own bicycle to Columbus Commons, there is plenty of bike parking at and near the park.
Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae.It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.Volvox diverged from unicellular ancestors approximately 200 million years ago.ach mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50,000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.
Each little dot you see is a tiny green algae with two flagella. With this the individual organisms propel themselves. They do this in a coordinated manner so that the entire colony can move in one direction. To see Volvox in locomotion is simply breathtaking. This image shows a colony with one large daughter colony. These develop from one one cell inside the sphere. Inside the daughter colony the third generation is already beginning to develop. As well as asexuality Volvox also uses sexual reproduction. The dark spheres are egg-cells. They are fertilized by small packages of sperm. The species depicted is Volvox aureus. It can be up to one millimetre or more in size. It can be found in clear water when the temperatures are not too low. The end of summer is the right time for a good catch with a plankton net.
