Biology : Protists Quiz

The taxonomic kingdom Protista is a collection of single celled organisms that do not fit into any other category. Protists are a group made up of protozoa, unicellular algae and slime molds. Protozoa are the oldest known group of heterotrophic life-that consume and transforms complex food particles into energy. Although protozoans are only made up of a single cell these organisms manage to perform all the basic tasks of life. The protozoans are divided into four major groups: the ciliates, the flagellates, the heliozoans, and the amoebas.
