Question

differentiate spermatogenisis and oogenisis​

Answer 1

Answer:

.....hope it will help you....

Explanation:

Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells.

______________________________

Oogenesis or ovogenesisis the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized. It is developed from the primary oocyte by maturation.

Answer 2

Answer:

Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas, oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into a embryo.

Let us have a detailed look at the difference between spermatogenesis and oogenesis.

Spermatogenesis vs Oogenesis

The difference between spermatogeneis and oogenesis are given below:

Spermatogenesis Oogenesis

The production of sperms from spermatogonia is known as spermatogenesis The production of eggs from oogonia is known as oogenesis

Occurs in testes Occurs inside the ovary

All stages are completed in testes The major part of oogenesis occurs inside the ovary. The last few stages occur in the oviduct.

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

Produces motile gametes Produces non-motile gametes

Equal cytokinesis occurs during the spermatogenesis producing four sperms Unequal cytokinesis occurs during oogenesis ultimately producing one ovum and four polar bodies
