GENERAL HISTOLOGY

Detailed explanation-1: -For fertilization to occur, the sperm must undergo the acrosome reaction. The acrosome is a membrane-bound organelle covering most of the head of the sperm. On interaction with the zona pellucida of the ova, the sperm releases proteolytic enzymes from the acrosome to penetrate and enter the ova.

Detailed explanation-2: -When the sperm cell finally reaches the egg cell, the plasma membranes of the two cells fuse together and the sperm releases its genetic material into the egg. At this point, fertilization has occurred, but we’re not done yet! Fusion also triggers the cortical reaction.

Detailed explanation-3: -fertilization, union of a sperm nucleus, of paternal origin, with an egg nucleus, of maternal origin, to form the primary nucleus of an embryo.

Detailed explanation-4: -Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes.
