Q

Sexual reproduction

A

Conjugation, specialized hyphae are + or - mating types, form a gametangium and fuse to form a zygospore

Q

Basidiomycota reproduction

A

Asexual; spores spreading

Sexual: two nuclei fuse to form zygote which then go through meiosis and form clusters of basidiospores. Hyphae fuse and form fruiting body.

Q

Zygomycota reproduction

A

Asexual: spores from sporangia germinate and grow into new fungus

Sexual: stolons of opposite mating types come together and form a gametangia. They form a diploid nucleus that makes a zygospore and then it germinates

Q

Ascomycota reproduction

A

Asexual: Conidia form a specialized hyphae called conidiophores

Sexual: occurs when haploid hyphae of two mating types grow close. Produce fruiting body in which sexual reproduction continues

Q

Stolons

A

Stemlike hyphae that run vertically

17
Q

Lichens

A

A symbiotic relationship between a fungi and a photosynthetic organism. The photosynthetic organisim gives the fungus products of photosynthesis while the fungus provides water and minerals

18
Q

Mycorrhizae

A

A fungi plant mutualistic relationship. The fungi hyphae help plants absorb water and minerals by helping plants increasing effective surface area of root system. Fungi release enzymes that free nutrients in soil. Plant in return provides fungus with products of photosynthesis

19
Q

Fungi jobs

A

Decomposers, parasites and symbiotic relationships
