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?

Saprobes

New Zealand’s native forests.

Parasites
