Volvox is an example of an organism that exists as a colony. A colony is a group of individual organisms that are physically attached to each other and live together in a coordinated way. Volvox is a green algae that exists as a spherical colony made up of thousands of individual cells. The cells in the colony are specialized and perform different functions such as reproduction, movement, and photosynthesis. The colony also has a protective outer layer that helps to shield it from predators and environmental stress.
