Answer 2

Answer:

Oogenesis is basically the production or development of an ovum.

Explanation:

Oogenesis, in the human female reproductive system, growth process in which the primary egg cell (or ovum) becomes a mature ovum. These cells, known as the primary ova, number around 400,000. The primary ova remain dormant until just prior to ovulation, when an egg is released from the ovary.

Oogenesis involves three key phases:

1. proliferation

2. growth

3. maturation

Proliferation:-

Proliferation is the process that results in an increase of the number of cells, and is defined by the balance between cell divisions and cell loss through cell death or differentiation.

Growth:-

Growth is the process in which primary egg cell becomes a mature ovum.

Maturation:-

Similar to a primary spermatocyte, every primary oocyte experiences two maturation divisions. However, the outcomes of maturation divisions under oogenesis are quite different to those which occur in spermatogenesis.These are known as the large secondary oocyte and a small polocyte.
