Write the adaptation in aquatic plants due to which
submerged leaves can bend in the flowing water.

Explanation

**Step-by-Step Solution:**

1. **Identify the Adaptation**: The main adaptation in aquatic plants that allows submerged leaves to bend in flowing water is the structure of their stems.

2. **Describe the Stem Structure**: Aquatic plants have long and narrow stems. This unique structure is crucial for their survival in water.

3. **Explain the Functionality**: The long and narrow shape of the stems allows them to bend easily when water currents flow over them. This flexibility helps prevent damage from the force of the water.
