Protista
The kingdom Protista is much more diverse than any other kingdom. Protists do not form a neat group that has certain traits in common instead they are extremely varied. It is just a grab-bag collection of organisms that do not fit into any other kingdom.
Protists are all eukaryotic but they vary widely, from single cells to huge 200ft long seaweeds. Some are photosynthetic, but others collect food like an animal. The main groups are the subkingdom algae (photosynthetic), protozoa (animal-like) and slime molds.
