Fungi
Introduction
Kingdom fungi
characteristics:
1. most are multicellular eukaryotic heterotrophs
2. cell wall of chitin
3. Reproductive structure called spores produced
on fruiting bodies
Spore = Single celled structure – small – why?
4. Body composed of mass of hyphae called a
mycelium
Septate vs. coenocytic (non-septate)
5. Saprophytes
6. Symbiotic fungi examples
