Answer:
All protists are eukaryotic organisms. This means that they have a membrane-enclosed nucleus and other cell organelles.
Most protists are aquatic, others are found in moist and damp environments.
Most are unicellular, however, there are a few multicellular protists such as the giant kelp.
They may be autotrophic or heterotrophic in nature.
Parasitism is also observed in some protistsKingdom Protista includes all eukaryotes that are not animals, plants, or fungi.
