KINGDOM FUNGI
Pages 527-536
Characteristics
◦Eukaryotes
◦Heterotrophic
◦Mostly multicellular
◦ Some unicellular (yeast)
◦Cell walls
◦Sessile (can’t move)
◦Secrete digesting enzymes
Structures
◦Cell wall
◦ Made of chitin: polysaccharide also found in exoskeletons
Structures
◦Hyphae: filaments that grow outwards
◦Mycelium: mat of hyphae
◦ Secretes enzymes to break down substances
◦ Nutrients then absorbed through the cell wall
Reproduction
◦Unicellular: undergoes budding
◦Multicellular:
◦ asexual: release genetically
identical spores to spread and
grow
◦ Sexual: (not common): two
hyphae fuse and then produce
and scatter genetically diverse
spores
Yeast
◦Unicellular fungi
◦Used in baking, produces CO2 which causes
bread to rise
