Cell of Fungi
● Unicellular
○ yeasts
○ molds
● Multicellular
○ mushrooms
● Cell have
○ nucleus
○ cytoplasm
○ ribosomes
○ mitochondria
● Have cell wall (клеточная стенка)
○ made of chitin (хитин)
○ chitin is type of carbohydrate

7.

8.

Multicellular Fungi Structure
● Hyphae (гиф)
○ branched tubular filaments (нити)
● Mycelium (мицелий)
○ network of hyphae
● Fruiting body (плодовое тело)
○ have reproductive cells - spores

9.

10.

Nutrition
● produce digestive enzymes (пищеварительные ферменты)
● saprotrophic nutrition
○ dead feeding
● Process
○ fungi secretes (выделяет) digestive enzymes to the soil
○ enzymes break down (расщепляет) nutrients in the soil
○ cell absorb (всасывает) nutrients from the soil

11.

12.

Reproduction
● Binary fission (бинарное деление)
○
yeasts
● Spores - reproductive cells
○
○
molds
mushrooms

Fungi Needs
● Need
○ moist (влажный) environment
○ warm (теплый) environment
○ nutrients (питательные вещества)
● Do NOT need
○ light

Role of Fungi
● Decomposers (разлагатели)
○
Break down dead organisms into smaller particles and create new compounds
● Cause disease
○
Athlete’s foot
● Food
