Question

What is the difference between a primary oocyte and a secondary oocyte?

Answer 1

Hint: Follicular development in the human female ovary is a crucial biological process that results in the generation of mature haploid ovum from the ovary's germinal epithelium, also known as the primordial cell. Follicular development begins during the embryonic or $$6$$ to $$8$$ months of a female's gestation period, is stopped at birth, and then resumes at puberty after sexual maturity.
Primary follicles containing primary oocytes, secondary follicles containing primary oocytes, and tertiary follicles containing mature secondary oocytes are among the follicles created during follicular development. Tertiary follicles next mature into Graafian follicles, releasing secondary oocytes for fertilisation with sperm.

Complete answer:

PRIMARY OOCYTE	SECONDARY OOCYTE
When the female is still in the womb, the primary oocyte develops.	At the onset of puberty, the secondary oocyte is generated.
Surrounded by secondary follicles.	Surrounded by tertiary follicles as well.
Chromosome number is $$46$$	Chromosome number is $$23$$
After mitosis, the primary oocyte is generated from oogonia and is diploid.	After meiosis I, the secondary oocyte is generated from the parent oocyte and is haploid.
When the gamete mother cell, oogonia, is halted in prophase-I of meiosis, it forms in the foetal ovary.	generated from a primary oocyte during puberty that completes its initial meiotic division and produces female gamete ova.

Note:
Oogenesis is a type of gametogenesis in which ova, also known as female gametes, are created and the resulting female gamete is called an ovum. The female gametes are commonly referred to as eggs, although the term egg can refer to several phases of development, therefore the meaning of an egg varies depending on the organism.
Oogenesis takes place in the ovaries' outermost layers. Oogenesis begins with the oogonium, a germ cell that undergoes mitosis to multiply. The three steps of the oogenesis process are as follows:
1. Prenatal.
2. Antral.
3. Pre-ovulatory.
