Spermatogenic Cells MCQ Questions and Answers

1. Which cell is the earliest spermatogenic cell in the process of sperm formation?

A. Spermatogonium

B. Primary spermatocyte

C. Spermatid

D. Spermatozoon

Correct Answer:
Spermatogonium

Explanation:
Spermatogonia are the earliest germ cells that divide and give rise to the later stages of spermatogenic cells.

2. Which spermatogenic cell undergoes meiosis I?

A. Spermatogonium

B. Primary spermatocyte

C. Secondary spermatocyte

D. Spermatid

Correct Answer:
Primary spermatocyte

Explanation:
The primary spermatocyte undergoes the first meiotic division to form secondary spermatocytes.

3. What is formed when a primary spermatocyte completes meiosis I?

A. Spermatogonia

B. Spermatozoa

C. Secondary spermatocytes

D. Spermatids

Correct Answer:
Secondary spermatocytes

Explanation:
Meiosis I of a primary spermatocyte produces two secondary spermatocytes.

4. Which cell is produced immediately after meiosis II of secondary spermatocytes?

A. Spermatogonium

B. Primary spermatocyte

C. Spermatid

D. Spermatozoon

Correct Answer:
Spermatid

Explanation:
Each secondary spermatocyte undergoes meiosis II and forms spermatids.

5. Which spermatogenic cell is haploid?

A. Spermatogonium

B. Primary spermatocyte

C. Spermatid

D. A diploid spermatocyte

Correct Answer:
Spermatid

Explanation:
Spermatids are haploid cells formed after meiosis and contain one set of chromosomes.

6. The transformation of spermatids into spermatozoa is called what?

A. Spermatogenesis

B. Spermiation

C. Spermiogenesis

D. Meiosis

Correct Answer:
Spermiogenesis

Explanation:
Spermiogenesis is the process in which spermatids develop into mature spermatozoa.

7. Which cell is the mature male gamete formed at the end of spermatogenesis?

A. Spermatogonium

B. Primary spermatocyte

C. Spermatid

D. Spermatozoon

Correct Answer:
Spermatozoon

Explanation:
A spermatozoon is the mature male gamete produced after the development of spermatogenic cells.

8. What is the correct order of spermatogenic cell development?

A. Spermatid, spermatogonium, primary spermatocyte, spermatozoon

B. Spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid

C. Primary spermatocyte, spermatid, spermatogonium, spermatozoon

D. Secondary spermatocyte, spermatogonium, spermatid, primary spermatocyte

Correct Answer:
Spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid

Explanation:
Spermatogenesis proceeds from spermatogonia to primary spermatocytes, secondary spermatocytes, and then spermatids before mature spermatozoa are formed.

9. Which spermatogenic cell is formed directly from a spermatogonium after its growth and development?

A. Primary spermatocyte

B. Secondary spermatocyte

C. Spermatid

D. Spermatozoon

Correct Answer:
Primary spermatocyte

Explanation:
A developing spermatogonium grows and differentiates into a primary spermatocyte.

10. How many spermatids are generally formed from one primary spermatocyte after completion of both meiotic divisions?

A. One

B. Two

C. Three

D. Four

Correct Answer:
Four

Explanation:
One primary spermatocyte undergoes meiosis I and meiosis II to produce four haploid spermatids.
