Human egg is larger than human sperm because it has

Options

A. Larger nuclues
B. More membranes
C. More cytoplasm
D. All the above

Answer

To answer the question "Human egg is larger than human sperm because it has:", we can break down the reasoning step by step.

### Step-by-Step Solution:

1. **Understanding the Size Difference**:
- The human egg (ovum) is significantly larger than the human sperm. The size of a human egg can be approximately 2 cm, while a sperm cell is about 0.05 mm.

2. **Components of the Egg and Sperm**:
- The human sperm consists of a head (which contains genetic material) and a tail (which provides motility). The head is small and streamlined for efficient movement.
- The human egg, on the other hand, contains not only the nucleus but also a substantial amount of cytoplasm.

3. **Role of Cytoplasm**:
- The cytoplasm in the egg is crucial as it contains nutrients, organelles, and materials necessary for the early stages of development after fertilization. This includes ribosomes and RNA, which are essential for protein synthesis.

4. **Comparison of Structures**:
- The egg has a larger nucleus and more cytoplasm compared to the sperm. The additional cytoplasm is what primarily contributes to the overall size of the egg.

5. **Conclusion**:
- Therefore, the primary reason the human egg is larger than the human sperm is due to the presence of **more cytoplasm**.

### Final Answer:
The correct option is **C. more cytoplasm**.
