  1. Protists and Fungi

  2. Protist Kingdom • The protist kingdom is sometimes called the “junk drawer” kingdom because it is filled with organisms that don’t fit easily into other kingdoms. • Even though some protists are unicellular and some are multi-cellular; and even though some are heterotrophs and some are autotrophs… • All protists are eukaryotes • Eukaryotes are organisms whose cells contain a nucleus.

  3. Three Types of Protists • Because protists vary greatly, scientists have proposed three ways of grouping protists. • There are three different types • Animal-like protists • Plant-like protists • Fungus-like protists

  4. Animal Like Protists • Like animals, animal-like protists have structures that enable them to move around. • And these organisms, like animals, are heterotrophs. • Animal-like protists are called protozoans and they are unicellular, unlike animals.

  5. Protozoans With Pseudopods • Pseudopods are temporary bulges of the cell membrane. • The cytoplasm flows into the bulge and the rest of the organism follows. • Amebas are protozoans that use pseudopods to move.

  6. Protozoans With Cilia • Cilia are hair like projections from cells that move with a wavelike pattern. • Cilia move organisms by acting like tiny oars. • Paramecium are protozoans that use cilia to move around.

  7. Other Protozoans • Some protozoans use flagella for movement. • Other protozoans called sporozoans are characterized by the way they live. • Sporozoans are parasites. • Parasites are organisms who live on or in another organism and harm that organism. • Hosts are the organisms to which the parasites live.

  8. Plantlike Protists • Most plantlike protists are called algae. • All algae are autotrophs.

  9. Fungus-like Protists • Fungus-like protists are heterotrophs, have cell walls, and use spores to reproduce. • Spores are tiny cells that are able to grow into a new organism

  10. Fungi Kingdom • Fungi Facts • Use spores to reproduce • Eukaryotes • Heterotrophs • Need warm moist places to grow • Multi-cellular fungi are arranged in hyphae • Hyphae are branching, threadlike tubes that make up the bodies of the fungi.

  11. Food for Fungi • Some fungi feed on the remains of dead organisms. • Ex: Mushrooms • Other fungi are parasites that break down chemicals in living organisms. • Ex: Athletes foot fungus
