Lab 6 - Reproductive Structures

Question 1

What is a sporangium?

Answer 1

A structure at the tip of hyphae in Zygomycota that produces asexual spores.

Question 2

What is a zygosporangium?

Answer 2

Thick-walled structure in Zygomycota formed during sexual reproduction after plasmogamy; contains zygospores

Question 3

What is a zygospore?

Answer 3

Diploid spore formed inside the zygosporangium after karyogamy; resistant and germinates into new hyphae.

Question 4

What is a basidiocarp?

Answer 4

The fruiting body of Basidiomycota (e.g., mushroom) that develops from dikaryotic mycelium and produces basidia.

Question 5

What are basidia?

Answer 5

Club-shaped cells on the basidiocarp where karyogamy and meiosis occur to produce basidiospores.

Question 6

What are basidiospores?

Answer 6

Haploid sexual spores produced on basidia in Basidiomycota; released to form new hyphae.

Question 7

What is an ascus?

Answer 7

Sac-shaped cell in Ascomycota where karyogamy occurs and meiosis produces ascospores.

Question 8

What is an ascocarp?

Answer 8

Fruiting body of Ascomycota that contains asci; releases ascospores.

Question 9

What are ascospores?

Answer 9

Haploid sexual spores produced inside an ascus in Ascomycota.

Question 10

What is a conidiophore?

Answer 10

Specialized hyphal stalk in Ascomycota (and some Basidiomycota) that produces asexual spores called conidia.

Question 11

What are conidia?

Answer 11

Asexual spores formed at the tips of conidiophores; disperse and germinate into new hyphae.
