Cell of germinal epithelium are___________(a) Cuboidal(b) Columnar(c) Squamous(d) Ciliated

The correct answer is (a) Cuboidal.

Explanation: The cells of the germinal epithelium are typically cuboidal in shape. The germinal epithelium refers to the layer of cells that lines the surface of the ovaries in females or the testes in males. These cells are responsible for the production of gametes (eggs or sperm). In both the ovaries and testes, the germinal epithelium consists of cuboidal cells that can undergo division to form germ cells. The cuboidal shape is characteristic of epithelial cells that are involved in secretion or absorption, which is essential for the function of the germinal epithelium in gametogenesis.

Thus, the correct answer is (a) Cuboidal.
