Slide1Ch 19: Diversity of ProtistsCh 19: Diversity of Protists

Slide2Kingdom ProtistaKingdom Protista G Eukaryotes that are not animals, plants or fungi.  They share some but not all of the features of plants, animals, and fungi. G They can be single celled or multi cellular, microscopic or large G Eukaryotes that are not animals, plants or fungi.  They share some but not all of the features of plants, animals, and fungi. G They can be single celled or multi cellular, microscopic or large
