· They are heterotrophs and ingest food by phagocytic while others photoautotrophs store energy via photosynthesis.

· Their movement are motile with Cilia ,flagella or pseudopodia

· Nearly all protists exist in aquatic environment including freshwater and marine water damp soil and even in snow .

· Aquatic protists –eg.,paramecium.

· Some protists can infect animals or plants they are parasite and thefore live in their host
