19.1 Diversity of Protists
KEY CONCEPT
Kingdom Protista is the most diverse of all the
kingdoms.
19.1 Diversity of Protists
Protists can be animal-like, plantlike, or funguslike.
• Protists are eukaryotes that are not animals, plants, or
fungi.
19.1 Diversity of Protists
• Animal-like protists consume other organisms.
– heterotrophs
– single-celled
19.1 Diversity of Protists
• Plantlike protists are photosynthetic.
– single-celled, colonial, or multicellular
– no roots, stems, or leaves
19.1 Diversity of Protists
• Funguslike protists decompose dead organisms.
– heterotrophs
– can move, whereas fungi cannot
19.1 Diversity of Protists
Protists are difficult to classify.
• Protista is one kingdom in the domain Eukarya.
19.1 Diversity of Protists
• Protist classification will likely change.
– Some protists are not closely related.
– Molecular evidence supports reclassification.
