Kingdom Fungi
Ch. 10 pg.364
Fungus are adapted for 2 main
functions
Absorption of nutrients
Reproduction
300 million years ago:
Fungus took a different evolutionary
pathway than plants
 They adapted to a heterotrophic way of life
and lost the ability to be autotrophs

Similarities between plants and
Fungi
Both are eukaryotic
 Both have cell walls
 Most are anchored in the soil or substrate
 Reproduction can be sexual or asexual or
both
 Both are stationary

Differences
Plants
Fungi
Have one nucleus per
cell
Are autotrophs
Often have many nuclei
per cell
Are heterotrophs
Most have roots
Have no roots
Have cellulose in the cell Often have chitin in the
walls
cell walls
Some reproduce by
None reproduce by seed
seed
Fungi are classified by how they
reproduce (produce spores).
Ex:
 Sac Fungi - yeast, morels, truffles
 Club Fungi – mushrooms, shelf fungi
 Imperfect fungi – disease causing fungi,
penicillium

Yeast & Morels
(Sac Fungi)
Truffels – Sac Fungi
Shitake Mushrooms – club fungi
Penicillium - Imperfect fungi
Terms
Hypha (hyphae) – branching filaments that
are usually on or below the surface of the
substrate
 Mycelium – a mesh of hyphae

Importance of Fungi
Decomposers – they are an important part
of nature’s recycling
 Benefit to humans – yeast is used to make
bread, wine & beer
 Penicillium – used to produce antibiotics
 Aspergillus – used to flavour soft drinks
 Food items –mushrooms, morels, truffles

Athlete’s Foot
Between the toes
And it gets worse…
Ringworm
Ringworm is a pathogenic fungi
Ringworm affects our pets too

How to treat ringworm infections
Yeast infections
Fungus Symbiosis


Symbiosis is a
relationship between
2 organisms that
survive together
LICHENS are an
example of this



Lichens are green
algae living with a
fungus
Green algae provide
the food through
photosynthesis
Fungi provide
protection by
surrounding the algae
and giving CO2 and
H2O
