| Animal-like protists | protists that ingest or absorb food after capturing or trapping it. |
| Cilia | small hair-like projections on the surface (cell membrane) of the cell used to sweep food into mouth-like structures and/or beat them in rhythm to move. |
| Flagellum (flagella) | a long whip-like tail used to move and/or catch food. |
| Fungus-like protists | protists that obtain their food by external digestions either as decomposers or as parasites. |
| Hyphae | long fibrous strands that allow the fungus to obtain water and nutrients. |
| Mycelium | a mass of hyphae. |
| Parasitic fungi | fungi that feed on other living organisms (host) and harm the host. |
| Plant-like protists | protists that produce food through photosynthesis. |
| Protists | usually single-celled organisms that that belong to the Kingdom Protista. |
| Pseudopod (false foot) | a finger-like projection of the cell membrane and cytoplasm used to catch food and/or for movement. |
| Saprophytic fungi | fungi that get their energy from decaying organic matter. |
| Symbiotic fungi | fungi that feed on other organisms (host) but do not harm the host. |
| Fungi | usually multi-celled organisms that are sessile (stuck in one place) and rely on external digestion to obtain food. |
