Excessive loss of water causes wilting of leaves, it can be prevented by

Options

A. Keeping the plant in bright light
B. Spraying the plant with alcohol
C. Applying vaseline on the leaf surface
D. Adding high amounts of fertilizers to the soil

Answer

To address the question regarding how to prevent excessive loss of water that causes wilting of leaves, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- Excessive loss of water from plants leads to wilting of leaves. This is primarily due to transpiration, where water evaporates from the leaf surface.

2. **Analyzing the Options**:
- **Option 1: Keeping the plant in bright light**:
- This option is incorrect. Bright light increases the rate of transpiration, leading to more water loss and further wilting.

- **Option 2: Spraying the plant with alcohol**:
- This option is not a viable solution for preventing wilting. Alcohol can harm the plant and does not address the water loss issue effectively.

- **Option 3: Applying Vaseline on the leaf surface**:
- This is the correct option. Applying Vaseline creates a barrier on the leaf surface, which blocks the stomata (pores) and reduces transpiration. This helps retain water in the plant, preventing wilting.

- **Option 4: Applying a high amount of fertilizer to the soil**:
- This option is also incorrect. While fertilizers can help in plant growth, excessive use can lead to salt accumulation in the soil, which can further stress the plant and contribute to wilting.

3. **Conclusion**:
- The most effective method to prevent wilting due to excessive water loss is to apply Vaseline on the leaf surface. This reduces transpiration and helps maintain water levels in the plant.

### Final Answer:
- The correct answer is **Option 3: Applying Vaseline on the leaf surface**.
