The gametes taking part in double fertilization are

Options

A. 5
B. 4
C. 3
D. 2

Answer

**Step-by-Step Solution:**

1. **Understanding Double Fertilization**: Double fertilization is a unique process that occurs in angiosperms (flowering plants). It involves two separate fertilization events that take place within the ovule.

2. **Identifying Gametes**: In double fertilization, two male gametes (sperms) are involved. These gametes are produced by the pollen grains.

3. **First Fertilization Event**: One of the male gametes fuses with the egg cell (the female gamete) to form a zygote. This is a diploid structure that will eventually develop into the embryo.

4. **Second Fertilization Event**: The second male gamete fuses with the secondary nucleus, which is formed from the fusion of two polar nuclei. This fusion results in the formation of the primary endosperm nucleus, which is a triploid structure.

5. **Conclusion**: Since two male gametes participate in the process of double fertilization (one forming the zygote and the other forming the endosperm), the answer to the question is **2**.

**Final Answer**: The gametes taking part in double fertilization are **2**.
