Fertilization leads to the formation of a zygote from "summary" of Human Biology by Cecie Starr,Beverly McMillan
The process of fertilization is a crucial step in sexual reproduction. It occurs when a sperm cell from a male fuses with an egg cell from a female. This fusion results in the formation of a zygote, which is the first cell of a new individual. During fertilization, the sperm cell penetrates the protective layers surrounding the egg cell and enters its cytoplasm. This triggers a series of changes in the egg, including the release of enzymes that prevent other sperm cells from entering. Once the sperm cell has entered the egg cell, their genetic material combines to form a single cell with a complete set of chromosomes. Thi...
