Question

Reproductive cells (germinal cells) are made up of the following epithelial cells-
(a)Cuboidal
(b)Columnar
(c)Squamous
(d)Sensory

Answer 1

Hint: It is a type of epithelium consisting of a single layer of cube-like cells. This type of epithelia is located on the surface of the ovaries, the lining of the nephrons, the walls of the renal tubules, and parts of the eye and the thyroid gland.

Complete answer:
The sexual organs are known as gonads. Testis and ovaries are lined with cuboidal epithelial cells known as germ cells. Germ cells are diploid and undergo mitotic division to form primary gametophyte, which is further undergoing meiosis to form haploid gametes.

Additional Information: Oogenesis, in the human female reproductive system, a process of development in which the primary egg cell (or ovum) becomes a mature ovum. These cells, known as the primary ova, number around 400,000. Primary ova remain dormant until just before ovulation when the egg is released from the ovaries. Oogenesis includes three main phases: proliferation, growth, and maturation, during which PGCs advance to primary oocytes, secondary oocytes, and then to mature ootides.
Spermatogenesis is the mechanism by which haploid sperm cells in the testis seminiferous tubules grow from the germ cells. The spermatids are transformed into sperm (sperm) by the sperm process. They grow into mature sperm cells, also known as sperm cells. It occurs primarily in the seminiferous tubules of the testes and can be divided into three stages, each of which is associated with different germ cell types: the proliferative phase: spermatogonia, and spermatocytes. Meiotic phase: spermatocytes containing spermatids.
So, the correct answer is ‘Cuboidal’.

Note: The germ cell is any biological cell that gives rise to the gametes of an organism that reproduces sexually. In many species, germ cells originate in the primitive streak and migrate to the developing gonads via the embryo's intestine.
