19.1: Protists The World of Protists What is a Protist? Kingdom Protista contains the most diverse group of organisms of all kingdoms Most are unicellular (diatoms), but some are multicellular (giant kelp). Some are heterotrophs, some are autotrophs and others are both. The characteristic that all protists share is that they are eukaryotes Protists are divided into animal-like protists, funguslike protists and plantlike protists. Protozoa: animal-like protist, all are unicellular Algae: plant-like protists, do not have roots, stems and leaves Unicellular algae produce most of the world?s oxygen and are the basis for aquatic food chains Fungus-like protists are able to move at some point in their life and do not have chitin in their cell walls What is a protozoan?

Eukaryotic Diversity Campbell AP Biology

Overview: AWorld in a Drop of Water ? In the past, taxonomists classified all protists in a single kingdom, Protista. ? However, it is now clear that Protista is in fact paraphyletic. ? Some protists are more closely related to plants, fungi, or animals than they are to other protists. ? As a result, the kingdom Protista has been abandoned. ? Various lineages are recognized as kingdoms in their own right. ? Scientists still use the convenient term protist informally to refer to eukaryotes that are not plants, animals, or fungi. Concept 28.1 Protists are an extremely diverse assortment of eukaryotes ? Protists exhibit more structural and functional diversity than any other group of organisms.
