We know that plants are harmed by excess water. But plants survive under flooded condition. How are they able to manage excess water ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Problem**: Plants can be harmed by excess water, leading to conditions like waterlogging. However, some plants can survive in flooded conditions. The key is to understand how they manage excess water.

2. **Role of Transpiration**: One of the primary ways plants manage excess water is through a process called transpiration. Transpiration is the loss of water vapor from the plant's surface, primarily through small openings called stomata.

3. **Increasing Transpiration Rate**: When faced with excess water, plants can increase their transpiration rate. This means they lose more water vapor to the atmosphere, which helps to reduce the amount of water they retain internally.
