Characteristics of Fungi• eukaryotic • most are multicellular • cell walls (made of chitin) • live on substrate / stationary • heterotroph (how do they eat?) • don’t store energy • has mycelium

How does Fungi absorb nutrients?
- The main structure is network of Mycelium (microscopic branches are called hypha)
- hypha excrete enzymes onto dead substrate
- hypha absorb digested nutrients
- digestion is extracellular

Deuteromycota (imperfect fungus)
• Produce only asexual spores
• Very common • Eg. ringworm,
athletes foot, Penicillin

Zygomycota
• Produce asexual spores
• Produce sexual zygospores
• Appear as small fuzzy black dotted mould
• Eg. Black spotted bread mould

Ascomycota
• Produce asexual spores
• Produce sexual spores in a sac
Eg. yeast, powdery mildew, morels

Basidiomycota• Produce sexual reproductive structures or fruiting bodies • Basidiospores
Eg. All Mushrooms, bracket fungus.

Fungal Roles in the Environment
Parasitic Fungi- feed off a host. ex. cordyceps

Fungal Roles in the Environment
Predatory Fungi- catches and kills prey

Fungal Roles in the Environment
Mutualistic Fungi- work together with other species in a beneficial way ex. Lichen = protista algae + fungi

Fungal Roles in the Environment
Saprophytic Fungi- live on dead and decaying material in the environment (recyclers)
