Funguslike protists include water molds, downy mildews, and slime molds. Like fungi, these protists are heterotrophs, have cell walls, and use spores to reproduce.
Plantlike protists, or algae, include euglenoids, dinoflagellates, diatoms, green algae, red algae, and brown algae. Like plants, these organisms are autotrophs.
Protozoan - An animal-like protist.
Pseudopod - A "false foot" or temporary bulge of the cell membrane used for feeding and movement in some protozoans.
Contractile vacuole - The cell structure that collects extra water from the cytoplasm and then expels it from the cell.
Cilia - The hairlike projections on the outside of cells that move in a wavelike manner.
Symbiosis - A close relationship between two organisms in which at least one of the organisms benefits.
Mutualism - A type of symbiosis in which both partners benefit from living together.
Spore - A tiny cell that is able to grow into a new organism.
Algae - A plantlike protist.
Pigment - A colored chemical compound that absorbs light, producing color.
