Normally in the head of a mature sperm cytoplasm is :-

Options

A. Present in large amount
B. Present in very moderate amount
C. Present in very little amount
D. Absent

Answer

**Step-by-Step Solution:**

1. **Understanding Sperm Structure**: Begin by familiarizing yourself with the structure of a mature sperm. A mature sperm consists of three main parts: the head, the middle piece, and the tail.

2. **Identifying the Head**: Focus on the head of the sperm, which contains two key components: the acrosome and the nucleus. The acrosome is a cap-like structure that contains enzymes necessary for fertilization, while the nucleus contains the genetic material.

3. **Cytoplasm in Sperm**: Consider the role of cytoplasm in cells. In most cells, cytoplasm is the gel-like substance that fills the cell and contains organelles. However, in the case of mature sperm, the head is primarily occupied by the acrosome and nucleus.

4. **Evaluating the Amount of Cytoplasm**: Since the acrosome and nucleus take up significant space in the head of the sperm, the amount of cytoplasm present is minimal. Therefore, we can conclude that the cytoplasm in the head of a mature sperm is not abundant.

5. **Analyzing the Options**: Review the provided options:
- Option A: Present in large amount - Incorrect, as the head is mostly occupied by the acrosome and nucleus.
- Option B: Present in moderate amount - Incorrect, as the cytoplasm is still quite limited.
- Option C: Present in very little amount - Correct, as established from our understanding of sperm structure.
- Option D: Absent - Incorrect, as there is some cytoplasm, albeit very little.

6. **Final Answer**: Based on the analysis, the correct answer is that in the head of a mature sperm, cytoplasm is present in very little amount.
