Time taken in Pinus from pollination to fertilization is

Options

A. 4 months
B. Four years
C. 13 months
D. Two years.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the time taken from pollination to fertilization in Pinus (a type of pine tree).

2. **Identifying the Components**: Pinus has both male and female cones. The male cones produce pollen grains, while the female cones contain ovules.

3. **Pollination Process**: The pollen grains from the male cones are carried by wind to the female cones. This is the process of pollination.

4. **Fertilization Process**: Once the pollen grains reach the female cones, they fertilize the ovules.

5. **Time Frame**: The entire process from pollination (when pollen reaches the female cone) to fertilization (when the ovule is fertilized) takes approximately 13 months.

6. **Conclusion**: Therefore, the time taken in Pinus from pollination to fertilization is **13 months**.

**Final Answer**: 13 months
