What is a Protist?

l      Kingdom Protista has been split into as many as 20 Kingdoms
l      Most protists are unicellular.
l      Most protists are aerobic.  Some are photoautotrophs (contain chloroplast), heterotrophs (absorbing organic molecules or ingesting larger food molecules), or mixotrophs (combine photosynthesis and heterotrophic nutrition)
l      Can divide protists into three categories: ingestive/protozoa (animal-like), absorptive (fungus like), and photosynthetic/algae (plantlike)
l      Most protists are motile, having cilia or flagella at some point.  These structures are extensions of the cytoplasm.
