Kingdom Protista includes eukaryotic organisms which don't easily fit into any other category. They vary by their method of locomotion and food-getting strategies. In terms of size, many members are unicellular, or, if multicellular in a colony for example, there is no evidence of tissue formation. They are simply cells that remain together without any higher level of organization. Some are animal-like, or Protozoa, some are plant-like, mainly algae, some are fungus-like, including slime molds. A common thread amongst this group is that they live in an aquatic or moist environment and have cells which contain organelles including an organized nucleus.
