Question

After fusion of sexual gametes in Mucor or Rhizopus, the resultant structure is known as?
A.Oospore
B.Cleistothecium
C.Zygote
D.Zygospore

Answer 1

Hint: Rhizopus rhizobia is an opportunistic disease, so it will only cause infection in people with weakened immunity. Fusarium wilt is the main disease caused by this fungus in humans. Although it is not fully understood, this disease is very dangerous and can be fatal.

Complete answer:
Cleistothecium: Conidia and flagellates are the key factors of Penicillium and play an important role in taxonomic description. The branch outline of the conidia is commonly used in the classification of Penicillium (Pitt, 1979). Conidia range from simple (isolated phialides) to very complex patterns, and the total symmetric or asymmetric pattern has several branching stages.
Zygote: A fertilized egg is a combination of sperm cells and egg cells. A zygote, also called a fertilized egg, starts from a single cell, but divides rapidly a few days after fertilization. After two weeks of cell division, the zygote eventually becomes an embryo.
Oospore: Eggs are thick-walled sexual spores that develop from ovum fertilized by certain algae, fungi, and oomycetes. It is believed that they evolved through the fusion of two species or chemically induced mycelial stimulation, leading to oospore formation.
Zygospore: The Zygomycota can reproduce sexually and asexually. In fact, sexual reproduction by zygotic spores after game corneal fusion is a clear feature of zygotic bacteria. Sexual reproduction is dominated by haploids, while asexual reproduction uses narculospores.

Hence the correct answer is OPTION(D)

Note: Sporozoites are produced by nuclear fusion of haploid cells. In fungi, zygotic spores are formed in zygotic spores after fusion of the special bud structure of the mycelium of the same (in the same type of fungus) or different mating types (in the different type of fungus), and may be chlamydial spores.
