How does the zygosporangium of rhizopus stolonifer function to ensure the survival of the species?

Zygosporangium protects the zygospore in unfavorable conditions.

Explanation:

Rhizopus stolonifer is a fungus also known as a black bread mold. Rhizopus is a member of Zygomycota and the most important species in the Rhizopus genus.

The fusion of two hyphae + and -  to produce a zygosporangium, a thick-walled body that is capable of surviving extreme conditions.

The main functions of this thick-walled body are to protect the zygospore until conditions become favorable. Nuclear fusion takes place within the zygosporangium producing 2n nuclei which are followed by meiosis, produce a sporangium that delivers haploid spores.

Thus, Zygosporangium protects the zygospore in unfavorable conditions.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
