Q

What are the characteristics of Volvox?

A
  • Volvox forms a sphere of 500 or more cells
  • 2 flagella that move the colony through the water
  • Daughter colonies that can be seen as darker spheres within the colony
  • Volvox causes “algae blooms” during the summer months
  • Fish hatcheries: blooms cause large numbers that can damage the gills of young fish
  • Gives water a fishy odor when present in large numbers
