Excessive aerenchyma is characteristic feature of

Options

A. Heliophytes
B. Xerophytes
C. Mesophytes
D. Hydrophytes

Answer

**Step-by-Step Solution:**

1. **Understanding Aerenchyma:**
- Aerenchyma is a type of ground tissue in plants characterized by large air spaces between cells. This tissue is important for gas exchange and buoyancy in aquatic environments.

2. **Identifying Types of Plants:**
- There are different types of plants based on their habitat:
- **Hydrophytes:** Plants that grow in water or in very moist environments.
- **Heliophytes:** Plants that thrive in full sunlight.
- **Xerophytes:** Plants adapted to dry conditions.
- **Mesophytes:** Plants that require moderate water and temperature conditions.

3. **Function of Aerenchyma:**
- Aerenchyma provides buoyancy to plants, preventing them from sinking in water. This is particularly important for plants that live in aquatic environments.

4. **Conclusion:**
- Given that aerenchyma is primarily found in plants that live in water, the excessive aerenchyma is a characteristic feature of **hydrophytes**.

**Final Answer:**
Excessive aerenchyma is a characteristic feature of **hydrophytes**.
