Question
Zygospores are formed in ______.
Zygospores are formed in ______.
Open in App
Solution
The correct option is D Mucor/Rhizopus
- Puccinia (basidiomycetes), Penicillium (ascomycetes), and Alternaria (deuteromycetes) do not produce zygospore.
- In the zygomycetes like Mucor, Rhizopus, etc., the male and female gametangia fuse together and the gametangial copulation leads to the formation of a zygospore. It contains many pairs of nuclei. Some of these pairs of nuclei fuse to produce diploid nuclei, while others degenerate. The diploid nuclei undergo reduction division before the zygospore germinates into stalked sporangium containing numerous haploid sporangiospores.
Thus, the correct answer is option D.
