Characteristics of Fungi
- All are eukaryotic; most are sessile (nonmotile)
- Nearly all are multicellular
Nutrition
- All are heterotrophic
- - parasitic
- - saprophytic
- - mutualistic symbionts
- - predators Fig

- Acquire nutrients by absorption
- Glycogen
- chitin
- hypha (-ae)
- mycelium
(-a)
- haustoria
Reproduction - generalized life cycle Fig
31.3 - both sexual and asexual
