threadlike filaments that are the basic structural units of multicellular fungi.
a network of branching hyphae; may serve to anchor the fungus, invade food sources, or form reproductive structures.
make up cells walls of fungi; makes them flexible and strong
hyphae grow into the host cells like a parasite and absorb the hosts nutrients
type of asexual reproduction where cells pinch off from the parent to form a new individual. (ex: yeast)
a sac or case of hyphae in which spores are produced.
Identify the characteristics of the fungi kingdom.
Mostly multicellular, eukaryotic, have chitin in cell walls, and heterotrophic.
Describe how a fungus obtains nutrients.
They use extracellular digestion, where food is digested outside of the fungus (by hyphae and enzymes) - the digestive products are then absorbed.
What role do fungi play in food chains?
They decompose dead animals, which puts nutrients back in the soil for more things to grow (autotrophs).
How are the terms hypha and mycelium related?
A mycelium is made up of hyphae.
Why would you expect to find several types of fungi growing in a bird's nest?
There are many things that make up a birds nest and fungi eat different kinds of organic material, such as feathers, twigs, or excrement.
Outline the steps you would take to calculate the appoximate number of spores in a puffball fungus with a circumference of 10 cm.
1) Divide puffballs into many small sections
2) Use sampling technique to estimate spores of one section
3) Multiply estimate by number of remaining sections
