Protists and Fungi

Protists and Fungi
2

• The protist kingdom is sometimes called the junk
  drawer kingdom because it is filled with
  organisms that dont 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.

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

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.

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.

Plantlike Protists

• Most plantlike protists are called algae.
• All algae are autotrophs.

11
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

12
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.

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
