NEET BIOLOGY

Detailed explanation-1: -The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg. One of these causes a change in the egg membrane(s), so that the attachment of and penetration by more than one spermatozoon cannot occur.

Detailed explanation-2: -zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Detailed explanation-3: -The mitosis of zygote results in the formation of an embryo. An embryo is a stage following the zygote stage. The process of formation of the zygote is known as fertilization. The process of formation of the embryo is known as embryogenesis.

Detailed explanation-4: -Final answer: The single cell produced after fertilization is called zygote.
