Plant-like protists make their own food, and many have cell walls made of cellulose. Animal-like protists cannot make their own food and ingest it. Some animal-like protests have âshells,â called tests, which are made of silica or calcium carbonate. Other animal-like protists lack a cell wall or protective test. The fungi-like protists are actually not evolutionarily related to fungi, although they do take in food by absorption. Like plants, however, their cell walls are made of cellulose.
