Assertion: Entomophilous plants produce less pollen when compared to anemophilous plants.
Reason: The wastage of pollen is reduced to the minimum in entomophilous plants because of directional pollination.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Entomophilous plants produce less pollen when compared to anemophilous plants."
- **Entomophilous plants** are those that rely on insects for pollination.
- **Anemophilous plants** are those that rely on wind for pollination.

2. **Analyzing the Characteristics of Pollen**:
- In entomophilous plants, the pollen grains are typically sticky and produced in smaller quantities. This is because insects help in targeted pollination, which reduces the need for excess pollen.
- In contrast, anemophilous plants produce a large quantity of small, non-sticky pollen grains. This is necessary because wind is a non-directional pollination agent, leading to a higher wastage of pollen.

3. **Understanding the Reason**: The reason states that "The wastage of pollen is reduced to the minimum in entomophilous plants because of directional pollination."
- Directional pollination occurs when insects carry pollen directly to the stigma of flowers, minimizing wastage.
- In contrast, wind pollination is random and can lead to significant pollen loss, as not all pollen reaches a stigma.

4. **Evaluating the Truth of Assertion and Reason**:
- Both the assertion and the reason are true.
- The reason correctly explains why entomophilous plants produce less pollen compared to anemophilous plants.

5. **Conclusion**: Since both the assertion and the reason are true, and the reason provides the correct explanation for the assertion, the correct option is that both the assertion and reason are true, and the reason is the correct explanation.

### Final Answer:
Both assertion and reason are true, and the reason is the correct explanation for the assertion.
