Objectives

What do you see?

What is the significance?

List the characteristics of fungiDo this in pairs.

List the characteristics of fungiEukaryotic, non photosynthetic, most are multicellular

autotrophs.

Different types

Molds Yeasts

Different types

Molds

Tangled mass of filaments.

Multicellular hyphae.

The dusty texture is caused by spores.

Different types

Yeasts

Unicellular fungi.

measuring 3–4 µm in diameter, although some yeasts can reach over 40 µm.

Different nutrition types

Absorb organic matter from their environment.

Secrete digestive enzymes and absorb throw the cell wall.

Most are saprophytic. What's the importance?

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

ParasitesUstilago maydisis a pathogenic plant fungus

that causes smut disease on maize.

PredatorsArthrobotrys conoides parasite of the ringworm.

Fungi causing diseases

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

Fungi in industry

Production of antibiotics like penicillin or cephalosporin, cortisone, ethanol and

used in genetic engineering.

Penicillium

Cephalosporium

Rhizopus

Saccharomyces

Molds very close to us

Interesting fact

100 are human pathogens.

Out of 100,000 known species:

1,000 are plant pathogens.
