General characteristics
Classification criteria
eukaryotes
heterotrophs
must feed off of others
mostly multicellular
except one-celled yeasts
AP Biology

Structure
Cells
long thread-like cells
multiple nuclei
cell wall
made from chitin
just like crab shells
chitin cell wall
septum

How do Fungi get their Nutrition?
fungal cells
Heterotrophs
secrete digestive enzymes
absorb digested material
into cell
predators
plant cell
membrane
paralyzing prey
parasites
feeding on living creatures
decomposer
breakdown dead remains
AP Biology
Cool…
Fungi live IN
their food!
Chocolate cake,
anyone?

Ecological Roles
Decomposers
recycle nutrients
Symbiotic Relationships
lichen
fungi + algae
pioneer species in
ecosystems
makes soil from bare rock
mycorrhizae
fungi + plants
AP Biology
enables plants to absorb more water
Mycorrhizae
Critical role in plant growth
extends water absorption of roots
