Protists

Protista

Protists are organisms that are classified into the kingdom Protista. The protists form a group of organisms that really do not fit into any other kingdom. Although there is a lot of variety within the protists, they do share some common characteristics. All protists are eukaryotic. That is, all protists have cells with nuclei. In addition, all protists live in moist environments. Protists can be unicellular or multicellular. Protists can be microscopic or can be over 100 meters (300 feet) long. Some protists are heterotrophs,, while others are autotrophs. Since protists vary so much, we will group them into three subcategories: animal-like protists, fungus-like protists, and plant-like protists.
