
What do you see?
What is the significance?

List the characteristics of fungi
Do this in pairs.

List the characteristics of fungi
Eukaryotic, non photosynthetic, most are multicellular autotrophs.

Molds Yeasts


Molds
 Tangled mass of filaments.
 Multicellular hyphae.
 The dusty texture is caused by spores.


Yeasts
 Unicellular fungi.
 measuring 3–4 µm in diameter, although some yeasts can reach over 40 µm.


 Absorb organic matter from their environment.
 Secrete digestive enzymes and absorb throw the cell wall.
 Most are saprophytic. What's the importance?

Saprobes
Entoloma hochstetteri, the ‘blue toadstool’, widespread in
New Zealand’s native forests.

Parasites
Ustilago maydisis a pathogenic plant fungus that causes smut disease on maize .

Predators
Arthrobotrys conoides parasite of the ringworm.


Allergies by mold spores.
Infections on skin, hair, nails and tissues.
Infections in internal organs by spores. Histoplasmosis.
Poisonous mushrooms.

Ringworm

Athlete’s foot

Candidiasis


Production of antibiotics like penicillin or cephalosporin, cortisone, ethanol and used in genetic engineering.

Penicillium
Cephalosporium
Saccharomyces
Rhizopus



Saccharomyces
Agaricus
