The Protoctista Kingdom - Protists
Protists (protoctists) are microscopic single-celled organisms. Some protists, such as Amoeba, have features like an animal cell. Others, such as Chlorella, have chloroplasts and are more like plants.

Some protoctists are pathogens. For example, Plasmodiumis, the pathogen that causes malaria.

Protists
Explores the history of eukaryotes while examining the diversity that exists in kingdom Protista reflected in organisms such as Euglena which have both animal and plant-like qualities. Looks at animal-like zooflagellates, sarcodines, ciliates, and sporozoans; fungus-like slime molds, and plant-like dinoflagellates, diatoms, and englenoids. Multicellular red, brown and green algae are examined and why modern biology places all three in kingdom Protista rather than kingdom Plantae explained.
