A protist is any single-celled or simple multicellular organism with a nucleus that isn't an animal, plant, or fungus, encompassing a diverse group of amoebae, algae, and other forms of microscopic life. Protists matter because they represent the evolutionary bridge from which animals, plants, and fungi all evolved, and they play important roles in aquatic ecosystems and food chains.
