A-General Characteristics

• Cell Cell-Multicellular
• Cell wall? made of carb chitin
• Food- Heterotrophs
• Secrete enzymes to break down their food
• Movement None

4

• Use Edible and some poisonous
• Where soil, water, mud, decaying plants/animals
• Called saprophytes? live on an organism and
  decompose it for food
• Purpose recyclers (along with bacteria)

5
Examples

• Mushrooms
• Yeast
• Bread mold
• Penicillium
• Truffles
• Athletes foot
• Produce cheeses, yogurt and cottage cheese

B-Structure

• 1-Hyphae-have enzymes (to digest food)
  thread-like filaments
• 2-Mycelium-network of hyphae like roots
• 3-Chitin-carb in cell wall strength
  flexibility

• Cap
• Stalk

Gills Basidia inside gills, small, lines
inside Spores attached to basidia
15
C-Symbotic Relationship

• 1-Lichen fungus grows with algae
• For Lichen provides structure and protection
• For Algae provides food for fungus
• What type of symbiotic relationship?

16
Fungus and Plants

• Form mycorrhizae which means fungus roots
• For Fungus gives plant?water nutrients
• For Plant gives fungus food
• What type of relationship?

17
D-Reproduction

• 1-Asexual- offspring identical to parent
• no variation
• Example Budding in which a piece of fungus
  breaks off and grows separate

• 2-Sexual-offspring varies from parent
• Example Spores in a fruit body (cap of a
  mushroom)
• -travels in the air
• -grows with right conditions
• (could be inhaled into lungs and cause infection)
