Fungi Flashcards
How do fungi get nutrients?
By secreting digestive juices onto a food source and then absorbing the dissolved food
Many fungi are (blank) which feed on dead plant or animal matter while other fungi are (blank)
Many fungi are decomposers which feed on dead plant or animal matter while other fungi are parasites
How can plants and fungi benefit from each other through a mycorrhiza?
Plants give fungi nutrients and fungi helps the plants roots absorb minerals
Mycorrhiza
A beneficial relationship between a plant and a fungus
Mycelium
The twisted mass that forms when hyphae grow together
Hyphae
Threadlike fungal filaments
Spores
The small reproductive cells that are protected by a thick cell wall
Fungi are made of (blank) cells
Eukaryotic
Where is mycelium found?
Underground
Describe the two types of asexual reproduction that take place in fungi
- The hyphae break apart
2. The production of spores
Sexual reproduction in fungi happens when special structures form to make what?
Sex cells
What type of fungus is shapeless and fuzzy?
Mold
What group does black bread mold belong to?
Threadlike
Where do most threadlike fungi live?
In soil
What are the spore cases on threadlike fungi called?
Sporangia
Name the four groups of fungi
Threadlike, sac, club, and imperfect
What are the two ways threadlike fungi reproduce
Spores and hyphae
What is the largest group of fungi?
Sac
What are some examples of sac fungi?
Yeast, powdery mildews, truffles, and morels
When sac fungi reproduce sexual, they form a sac called a (blank)
ascus
Name two ways sac fungi are useful
Bread and alcohol
Budding
A form of asexual reproduction used by yeast
Chestnut blight
A disease caused by sac fungi
Club fungi
The group of fungi that mushrooms belong to
Basidia
Club Like structures on club fungi
Bracket fungi
A fungi that grows outward from wood and forms small shelves
Aflatoxin
A poison produced by an imperfect fungi
Penicillium
A fungi used to make antibiotics
Why do mushrooms appear in circles?
They grow at the edges of the mass hyphae
Bracket fungi, puffball, smuts, and rust are all (blank) fungi
Club
Imperfect fungi do not reproduce (blank)
Sexually
A common human skin disease caused by imperfect fungi is (blank)
Athletes foot
A lichen is a combination of what two organisms?
Fungi and algae
Because lichen produce their food through photosynthesis what group do they belong to Consumers Parasites Producers Host
Producers
What allows lichen to live in even the driest environments without drying out?
Their protective walls
Why can lichen grow on rocks?
Because lichen only need air, light, and minerals
Tell how a lichen changes its surroundings in a way that allows other organisms to live there
When bits of rock and dead lichen fill in cracks soil is made
Why are lichen so easily affected by air pollution?
Because lichen absorb water and minerals from the air
Fungi
Eukaryotic heterotrophs that have rigid cell walls and no chlorophyll
