Question

Select the correct sequence with respect to the process of spermatogenesis.
a) Primary spermatocyte
b) Primordial cell
c) Secondary spermatocyte
d) Spermatogonia
e) Spermatids

• A. b\(\rightarrow\)d\(\rightarrow\)c\(\rightarrow\)e\(\rightarrow\)a
• B. b\(\rightarrow\)d\(\rightarrow\)a\(\rightarrow\)c\(\rightarrow\)e
• C. b\(\rightarrow\)a\(\rightarrow\)c\(\rightarrow\)d\(\rightarrow\)e
• D. b\(\rightarrow\)a\(\rightarrow\)c\(\rightarrow\)e\(\rightarrow\)d

Hint:

Start with primordial germ cells and follow the stages of meiosis.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Spermatogenesis forms sperms from primordial germ cells in a fixed order.

Step 2: Follow the stages
Primordial germ cells (b) divide mitotically to give spermatogonia (d).
A spermatogonium grows into a primary spermatocyte (a), which completes meiosis I to form secondary spermatocytes (c).
Meiosis II converts these into spermatids (e).

Step 3: Write the sequence
The order is b, d, a, c, e.

Final Answer:
The correct sequence is b to d to a to c to e. \[ \boxed{\text{(B) }b\rightarrow d\rightarrow a\rightarrow c\rightarrow e} \]
