Sperms contribute to the development of zygote by providing:

Options

A. cytoplasm
B. centrioles
C. nutrients
D. required activation enzymes

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what sperms contribute to the development of the zygote. A zygote is formed when a sperm (male gamete) fertilizes an ovum (female gamete).

2. **Identifying the Components**: The options provided are:
- Option 1: Cytoplasm
- Option 2: Centrioles
- Option 3: Nutrients
- Option 4: Required activation enzymes

3. **Analyzing the Role of Sperm**:
- The sperm is a male gamete and is significantly smaller than the ovum.
- The ovum contributes most of the cytoplasm and nutrients necessary for the early development of the zygote.

4. **Focusing on Centrioles**:
- The sperm contains centrioles, which are essential for cell division.
- The female gamete (ovum) lacks centrioles, which means that for the zygote to undergo division and development, centrioles must be provided by the sperm.

5. **Conclusion**:
- Since the centrioles are crucial for the process of cell division and are provided by the sperm, the correct answer is that sperms contribute to the development of the zygote by providing centrioles.

6. **Final Answer**: The correct option is **Option 2: Centrioles**.
