Explanation / Answer

Solution:

?1.The sperm cell containing? 23 chromosomes reaches the corona radiata , the follicular cells that surround the unfertilised egg.

2. The acrosome of the sperm cell releases a protein-digestive enzymes that aids in penetration of the zona pellucida that surrounds the cell membrane of the oocyte.

3.Then the membrane of the sperm cell fuses with the membrane of the secondary oocyte.

4.Following the merger of the two nuclei ( one from the sperm cell and one from the oocyte), the resulting single cell , called a Zygote , contain 46 chromosomes.

5.The oocyte then divides unequally to form a cell and a tiny second polar body thus completing meiosis and fertilization.

Explanation:

Fertilization is the process of fusion of a sperm and an oocyte (egg). Each of these reproductive cells is a haploid cell containing half of the genetic material ( 23 chromosomes) needed to form a diploid single cell called zygote with 46 chromosomes that develop in to new human being.

The process of fertilization is described below step by step in brief :-
