Protists are generally single celled organisms grouped under the Protista Family, but recently they have been reconsidered to be a grouping of organisms that have little in common but that they do not fit in elsewhere and while they do have complex organelles, they do not differentiate tissues. They can have various trophic modes, motility, cell coverings, and life cycles.
