WebSome species exhibit both autotrophic and heterotrophic nutrition. The great diversity of protist characteristics supports theories about the antiquity of the protists and of the ancestral role they play with respect to other eukaryotes. The architectural complexity of most protist cells sets them apart from the cells of plant and animal tissues.
