Fungi

Question 1

How do Fungi absorb nutrients

Answer 1

Heterotrophs
Do NOT ingest food
Excrete hydrolytic enzymes
Decomposers, parasites, mutualists

Question 2

explain asexual reproduction in filamentous Fungi

Answer 2

Hyphae are haploid (including nuclei)
Produce spores asexually
Spores grow into new mycelia
Commonly called “moulds”

Question 3

explain asexual reproduction in single cell Fungi

Answer 3

budding

Question 4

explain sexual reproduction in fungi

Answer 4

Haploid hyphae
Hyphae release pheromones
Compatiable mate extend towards eachother and fuse

Question 5

what is the heterokaryotic stage

Answer 5

stage when haploid nuclei do not immediately fuse, may take hours to centuries

Question 6

Pros of Fungi in terms of ecological importance

Answer 6

Decomposers
Mutualists (eg lichen; funal-algal mutalisms)
Have role in defining (bacterial) communities and interacting with immune cells
Food
Nutrients to plants

Question 7

Cons of Fungi in terms of ecological importance

Answer 7

destroy crops, some cause human disease (ringworm)

Question 8

are fungi closer to plants or animals

Answer 8

similar DNA sequence, fungal flagella, and heterotrophs like animals. Store glucose as glycogen like plants
