GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The zygote’s single cell contains all of the 46 necessary chromosomes, getting 23 from the sperm and 23 from the egg. The zygote phase is brief, lasting only about four days. Around the fifth day, the mass of cells becomes known as a blastocyst. The embryo develops from the blastocyst.

Detailed explanation-3: -A zygote, also called a fertilized egg, is the phase of conception where the egg and sperm join to form a single cell.

Detailed explanation-4: -A zygote is a fertilized eukaryotic cell. In biology, medical science, and other allied fields, including psychology, the term “zygote” is used to refer to a cell that forms after the union of sex cells (also called gametes). Reproduction by sexual means involves male and female gametes.

Detailed explanation-5: -From Egg to Embryo The fertilized egg (zygote) divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst.
