|
threadlike filaments that are the basic structural units of multicellular fungi.
|
Hypha
|
|
|
a network of branching hyphae; may serve to anchor the fungus, invade food sources, or form reproductive structures.
|
mycelium
|
|
|
make up cells walls of fungi; makes them flexible and strong
|
chitin
|
|
|
hyphae grow into the host cells like a parasite and absorb the hosts nutrients
|
haustoria
|
|
|
type of asexual reproduction where cells pinch off from the parent to form a new individual. (ex: yeast)
|
budding
|
|
|
a sac or case of hyphae in which spores are produced.
|
sporangium
|
|
|
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 |
