Fungi
Name 5 characteristics of fungi.
Fungi:
1. are eukaryotes
2. are heterotrophs
3. use spores to reproduce
4. have cell walls
5. need warm and moist places
What are 3 functions of hyphae?
Functions of hyphae:
1. give the fungus its shape
2. absorbs water and nutrients
3. anchors the fungus
Describe 2 ways that hyphae
determine fungi structure.
Loosely tangled hyphae are fuzzy
looking (like old food).
Tightly packed hyphae have a
definite shape (like a mushroom).
How do fungi reproduce?
•
•
•
Fungi produce millions of spores.
Spores are lightweight and can be
carried by water or air.
Spores are produced in fruiting
bodies.
How do fungi reproduce when there
is adequate food and moisture?
Fungi reproduce asexually and the
offspring are genetically identical.
What fungus does not produce
spores? How does this organism
reproduce?
Yeast does not produce spores and
reproduces asexually by budding.
How do fungi reproduce during
unfavorable growing conditions?
Fungi reproduce sexually and
produce offspring that are genetically
different.
Name 4 good things about fungi.
Good things:
1. decomposers/recyclers
2. fight disease
3. live in symbiosis with many
organisms
4. food
Give examples of disease-causing
fungi.
Disease-causing fungi:
1. kill crops/trees
2. athlete’s foot
3. ringworm
What are lichens?
Lichens are fungi + algae.
