Structure• Cell walls are made of a polysaccharide called chitin, (also

found in the exoskeleton of insects, crustaceans).• Cytoplasm and organelles can move from one cell to another in

the multicellular organism.

Parts and Function• Mycelium – extensive network of cells below ground absorbing

nutrients, grows rapidly and has a large surface area• Hyphae – reproductive part above ground (fruiting body)

Reproduction - asexual1. Budding occurs in yeast

2. Most fungi release spores (haploid) from gills in the sporangium
