<p><strong>Solution :</strong></p>
<p>Germinal epithelial cells divide repeatedly to form multiple diploid oogonia, and these oogonia grow to form primary oocytes. These will get surrounded by granulose cells and forms a primary follicle.</p>
<p>Then it will be surrounded by the granular cells to form secondary follicles. This secondary follicle converts into tertiary follicle by adding more granulosa cells. The primary oocyte within the tertiary follicles undergoes meiotic division to form a secondary oocyte and a haploid polar body. This tertiary follicle then matures into a Graafian follicle which, in turn, ruptures to release a secondary oocyte or ovum.</p>

<p>In the figure, ‘a’ shows the zygote formation after the fusion of male and female gametes and ‘b’ shows the entrance of the zygote to the isthmus.<br>
Cleavage stage: Within the isthmus, the zygote formed by the fusion of the male and female gamete, enters the two-cell stage known as cleavage.<br>
Blastomere: The cleavage formed, undergoes mitosis. At first, it forms a 2, then 4, then 8 and finally 16 cells stage. These daughter cells are called blastomere.<br>
Morula: The 8-16 cell blastomere is known as a morula. This morula divides continuously to form a blastocyst and moves into the uterus.<br>
The trophoblast is the layer arranged in the blastocyst. The trophoblast layer gets attached to the endometrium lining of the uterus, the inner cells that form an embryo after differentiation. Uterine cells divide to cover the blastocyst. Later it gets embedded in the endometrium of the uterus, known as implantation.</p>

<p>The mammary gland is a paired organ which has an undeveloped duct system and adipose tissue.</p>
</li>
<li>
<p>The secretion of oestrogen and progesterone increases when a woman gets pregnant and produces milk when a glandular system is in the mammary glands.</p>
</li>
<li>
<p>The glandular tissue of each breast forms mammary lobes consisting of clusters of cells known as alveoli.</p>
</li>
<li>
<p>These alveoli cells start secreting milk that is stored within the cavities of the alveoli and open into the mammary tubules and join with a duct.</p>
</li>
<li>
<p>The mammary ampulla is formed by the formation of a number of mammary ducts joining.</p>
