What is the correct sequence of sperm formation?

Options

A. Spermatid, Spermatocyte, Spermatogonia, Spermatozoa
B. Spermatogonia, Spermatocyte, Spermatozoa, Spermatid
C. Spermatogonia, Spermatozoa, Spermatocyte, Spermatid
D. Spermatogonia, Spermatocyte, Spermatid, Spermatozoa

Explanation

To answer the question about the correct sequence of sperm formation, we can break down the process step by step:

### Step-by-Step Solution:

1. **Spermatogonia**: The process begins with spermatogonia, which are the sperm mother cells located on the inner wall of the seminiferous tubules in the testes. These cells undergo mitotic division to increase their numbers.

2. **Primary Spermatocyte**: Some of the spermatogonia differentiate into primary spermatocytes. This is a crucial step as these cells are destined to undergo meiosis.

3. **Secondary Spermatocyte**: The primary spermatocytes then undergo the first meiotic division, resulting in the formation of secondary spermatocytes.

4. **Spermatids**: The secondary spermatocytes undergo the second meiotic division, which produces four haploid cells called spermatids.

5. **Spermatozoa**: Finally, the spermatids undergo a transformation process called spermiogenesis, where they develop into mature sperm cells known as spermatozoa.

### Correct Sequence:
The correct sequence of sperm formation is:
1. Spermatogonia
2. Primary Spermatocyte
3. Secondary Spermatocyte
4. Spermatids
5. Spermatozoa
