A characteristic feature of hydrophytes is

Options

A. Aerenchyma
B. Well developed phloem
C. Floating leaves
D. Submerged leaves.

Answer

### Step-by-Step Solution:

1. **Understanding Hydrophytes**:
- Hydrophytes are plants that are adapted to live in aquatic environments, either partially or fully submerged in water.

2. **Identifying Characteristics of Hydrophytes**:
- Hydrophytes have several adaptations that help them survive in water. These adaptations include specialized structures that facilitate buoyancy, gas exchange, and nutrient absorption.

3. **Evaluating the Options**:
- The options given are:
- A. Aranchyma
- B. Well-developed phloem
- C. Floating leaves
- D. Submerged leaves

4. **Analyzing Each Option**:
- **Aranchyma**: This is a spongy tissue that contains air spaces, allowing for buoyancy and gas exchange in aquatic plants. It is a characteristic feature of hydrophytes.
- **Well-developed phloem**: While phloem is important for nutrient transport, it is not a distinguishing feature of hydrophytes.
- **Floating leaves**: Many hydrophytes have floating leaves, but this is a result of the presence of aranchyma.
- **Submerged leaves**: These are not characteristic of all hydrophytes and do not define them.

5. **Conclusion**:
- The correct answer is **Aranchyma**, as it is a defining feature of hydrophytes, providing them with the necessary adaptations to thrive in aquatic environments.

### Final Answer:
A characteristic feature of hydrophytes is **Aranchyma**.
