The zygosporangium of Rhizopus stolonifer function to
ensure the survival of the species by remaning dormat during unsuitable
conditions. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
zygosporangium serves to protect the zygospore during unfavorable growth conditions which in turn germination to form new mycelium once the conditions favor growth.
Explanation:
In <em>Rhizopus stolonifer</em>, zygospore is formed by fusion of two gametangia from compatible strains during unfavorable growth conditions. The zygospore secrete a thick wall around it, the whole structure is called as zygosporangia. It serves as resting spore and gives rise of new mycelium by germination of zygospore upon arrival of favorable growth conditions.
