Question

What is difference between spermatogenesis and oo genesis?

Answer 1

Explanation:

The difference between spermatogenesis and oogenesis are given below:

Spermatogenesis:-

1. The production of sperms from spermatogonia is known as spermatogenesis.

2.Occurs in testes.

3. All stages are completed in testes.

4.It is a continuous process.

5.Produces motile gametes.

6.Equal cytokinesis occurs during the spermatogenesis producing four sperms.

Oogenesis:-

1. The production of eggs from oogonia is known as oogenesis.

2. Occurs inside the ovary.

3. The major part of oogenesis occurs inside the ovary. The last few stages occur in the oviduct.

4. It is a discontinuous process. The early stages take place in the foetus and the rest in later stages of life.

5. Produces non-motile gametes.

6. Unequal cytokinesis occurs during oogenesis ultimately producing one ovum and four polar bodies.
