Question

Which of these spores are characteristic of the black bread mold Rhizopus?
A.Arthrospore and Ascospore
B. Ascospore and Zygospore
C. Arthrospore and Blastospore
D. Sporangiospore and Zygospore

Answer 1

Probably 'D' if Asexual and Sexual modes are considered.

Answer 2

Answer:

Sporangiospore and Zygospore

Explanation:

Stolon's, rhizoids, and typically unbranching sporangiophores make up the body of branching mycelia that characterizes Rhizopus fungus. In order to create multiple nonmotile multinucleate spores for asexual reproduction, the black sporangia at the tips of the sporangiophores are rounded.

In the life cycle of many fungi and protists, nuclear fusion of haploid cells results in the formation of zygospore, a thick-walled, diploid reproductive stage. They do not move.
