Chapter 19

Some protists are heterotrophic (eat to get energy) and some are autotrophic (make their own food through photosynthesis). These are often called animal–like or plantlike.

Some protists can live as a colony (a cluster of cells that live together).

Evolution of Protista

Protista are a very diverse group. They contain many types of organisms. Scientists are now finding that all of these organisms are not as closely related to each other and so they might be split into multiple kingdoms in the future.
