Important New Vocabulary

• Hyphae Mass of many-celled, threadlike tubes
  forming the body of a fungus.
• Spores Waterproof reproductive cell of a
  fungus.
• Decomposer Organism that breaks down decaying
  organic material and returns it to the soil.

3
Main Characteristics

• Most fungi share three important characteristics
• Eukaryotes
• Use spores to reproduce
• Heterotrophs

4
How do fungi obtain food?

• The fungus grows hyphae into its food source.
• Digestive chemicals ooze from the hyphae into the
  food.

5
The digestive chemicals break down the food
into small substances that can be absorbed into
the hyphae.

Fungi Reproduction

• Asexual By budding a small yeast cell grows
  from the body of a fungus. It eventually breaks
  away. (Pg 226 in your book.)
• Sexual -The hyphae of two fungi grow together and
  genetic material is exchanged. A new structure
  grows from the joined hyphae.

Roles of Fungi

• Environmental decomposers
• Food source
• Cause diseases
• Fight diseases (Penicillin powerful antibiotic)

Fungi Classification

• Four groups based on the shape of the
  spore-producing structures, and ability to
  reproduce sexually
• a. Threadlike - 600 species of molds, produce
• spores in their hyphae.

9

• b. Sac - 30,000 species, produce spores in
• structures that look like sacks.
• c. Club - 25,000 species,
• produce spores in structures
• that look like clubs

10

• Imperfect Fungi 25,000 species, do not
  reproduce sexually, Penicullium is in the group.
