Question

Match the following columns and select the correct option.

$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \text{(a)}& \text{Placenta}& \text{(i)}& \text{Secretes hormones which are either proteins or steroids in chemical nature}\\ \text{(b)}& \text{Zona pellucida}& \text{(ii)}& \text{Acellular layer of the ovum formed by secondary oocyte}\\ \text{(c)}& \text{Cells of Sertoli}& \text{(iii)}& \text{Rich in calcium, fructose and certain enzymes}\\ \text{(d)}& \text{Seminal plasma}& \text{(iv)}& \text{Release certain factors which help in spermiogenesis}\end{array}$

• A. (a) - (i), (b) - (iv), (c) - (ii), (d) - (iii)
• B. (a) - (iii), (b) - (ii), (c) - (iv), (d) - (i)
• C. (a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
• D. (a) - (i), (b) - (ii), (c) - (iv), (d) - (iii)

Answer 1

The correct option is D (a) - (i), (b) - (ii), (c) - (iv), (d) - (iii)

Placenta secretes hormones of different chemical natures (proteins and steroids). Layer of ovum secreted by itself is zona pellucida which is acellular layer formed by glycoproteins. Cells of Sertoli secrete certain factors which are responsible for spermiogenesis.
