1. Chapter 3: Protists & Fungi
Review of Topics

2. Protists
Animal-like protists, or protozoa, are heterotrophs and unicellular.
Protozoans can move by pseudopods, cilia, or flagella.
Plantlike protists are autotrophs. Most are unicellular but some are multicellular.
Most algae plays an important role in the food chain. It also is responsible for adding much of the oxygen into the atmosphere.
Funguslike protists are heterotrophs and use spores to reproduce.

3. Fungi
Hyphae are the branching, thread-like tubes that make up the bodies of multicellular fungi.
Fungi reproduce by releasing spores that will be carried away to new locations.
Fungi are decomposers, they can are used in medicines, they can cause diseases.
Plants with a root-fungus association can grow to be larger and healthier with the help of the fungus.
