Vedclass · Answer

(A) During the process of fertilization,the sperm comes in contact with the zona pellucida layer of the ovum. The acrosome of the sperm releases enzymes (sperm lysins) that help the sperm penetrate the egg. Upon contact,the plasma membrane of the sperm fuses with the plasma membrane of the ovum. The head of the sperm,containing the nucleus,and the centrioles enter the cytoplasm of the ovum. The middle piece (containing mitochondria) and the tail usually remain outside or degenerate. Therefore,only the head enters the ovum.
