Mention the disadvantages of transpiration in plants.

Explanation

**Step-by-Step Solution:**

1. **Definition of Transpiration**: Transpiration is the process through which plants lose water in the form of water vapor, primarily from their leaves.

2. **Wilting of Leaves**: One of the primary disadvantages of transpiration is that excessive water loss can lead to wilting of leaves. When a plant loses too much water, it struggles to maintain turgor pressure, causing the leaves to droop and become limp.

3. **Permanent Damage**: If transpiration continues at a high rate, it can result in permanent damage to the leaves. This damage can hinder the plant's ability to photosynthesize effectively.
