Protists, like monerans, are microscopic. Some examples are amoeba, paramecium, kelp, and diatom. Protists vary widely in shape, size, and form, and can be unicellular or multicellular. Protists are eukaryotic, meaning they have a nucleus and other structures in their cells, which are not found in prokaryotic cells.
