What do the cells in the front of a volvox typically develop to help swim towards light?
vertebrates
tumors
sunspots
eyespots
Each Volvox , shown in Figure above , is a colonial organism. It is made up of between 1,000 to 3,000 photosynthetic algae that are grouped together into a hollow sphere. The sphere has a distinct front and back end. The cells have eyespots, which are more developed in the cells near the front. This enables the colony to swim towards light.
