The nucleus of a sperm id located in :

Assertion : The nucleus of sperm fuses with the nucleus of ovum , before the formation of ootid . Reason : Diploid nuclear status of organism is essential for its development .

Assertion : The nucleus of sperm fuses with the nucleus of ovum , before the formation of ootid . Reason : Diploid nuclear status of organism is essential for its development .

Assertion : Acrosome is a small cup like pointed structure at the tip of the nucleus of sperm, which helps the sperm to pentrate the ovum during fertilization. Reason : Acrosome contains a proteolytic enzyme, hyaluronidase popularly known as sperm lysin which helps to penetrate the ovum during fertilization.

What is the role of proximal centrioles located in the neck of the sperm ?

Read the following text and answer the following questions on the basis of the same: During sexual reproduction, the male inserts the sperm into the female reproductive tract, and sperm receive by the ovary and after that sperm fuse with the egg (ovum) in the ampullary region, this process is called fertilization, haploid nucleus of sperm fuse with that of ovum to form Diploid zygote. The phenomenon of sperm activation in mammals is known as.

Assertion (A): All copulations do not lead to the fertilisation and pregnancy. Reason (R): Fertilisation can occur only if the ovum and sperms are transported simultaneously to the ampulllary-isthmic junction.

Site of fusion of sperm with an ovum.

The part of the sperm which contains the nucleus is
