Fungi Flashcards
Give example of multicellular fungi:
Mushrooms & Moulds
Give example of unicellular fungi:
Yeast
What are hyphae (single=hypha)?
Thread-like filaments of cells in fungi
What is a mycelium?
Network of fungal hyphae
How do moulds feed?
By absorbing nutrients from dead (or sometimes living) material. This means that they are found wherever these materials are present (e.g. on rotten fruit)
What happens if you leave bread exposed in air for a few days?
It will become mouldy
Mould spores carried in the air have landed on the fruit and grown into a mycelium of hyphae.
What is mucor?
A mould fungi
MUCOR
What type of nutrition do fungi?
Saprotrophic
What does Saprotrophic mean?
Type of Nutrition carried out by most fungi and bacteria
Where dead organic material is digested OUTSIDE of the body of the organism by extracellular enzymes
What happens when the food is used up?
The mould infects another source of food by producing more spores
Hyphae secrete digestive enzymes onto the food, breaking it down into soluble substances like sugars, which are then absorbed by the mould
