General characteristics
 Classification criteria
_____________________
 _____________________

 feed by absorption

mostly multicellular
 except unicellular yeasts

AP Biology
sexual & asexual reproduction
Fungal Structure
 Fungal body

mycelium
 thread-like cells
 hyphae
 Cells

multiple nuclei
 Cell wall

chitin
 just like crab shells
AP Biology
Internal structure
 Eukaryotic cells

long, thread-like cells
 filamentous

incomplete divisions
between cells
 septum

multiple nuclei
Aaaaah,
structure–function
relationship!
AP Biology
chitin cell wall
septum
pore
nuclei
Modes of Nutrition
 Heterotrophic
fungal hypha
secrete digestive enzymes
 feed by absorption

 parasites
 feeding on living creatures
plant cell
 predators
membrane
 paralyzing prey
 decomposer
 breakdown dead remains
AP Biology
Fungi live IN
their food!
It’s like you living
in Chocolate cake!

Ecological Roles
 ___________________

recycle nutrients
 Symbiotic Relationships

_____________________
 fungi + algae
 pioneer species in
ecosystems
 makes soil from bare rock

Lichens are fungi
that have discovered
agriculture!
_____________________
 fungi + plants
AP Biology
 enables plants to absorb more water
Mycorrhizae
 Critical role in plant growth

extends water absorption of roots
without
mycorrhizae
Endomycorrhiza
AP Biology
Ectomycorrhiza
with
mycorrhizae
Reproduction
 Asexual

budding in yeast
 Sexual

spores
 spread by wind

