Aerenchyma is found in :

Options

A. lithophytes
B. xerophytes
C. hydrophytes
D. sciophytes

Explanation

**Step-by-Step Solution:**

1. **Understanding Aerenchyma**: Aerenchyma is a type of parenchyma tissue that contains air spaces. It is primarily found in certain types of plants, particularly those that grow in aquatic environments.

2. **Identifying Plant Types**: The question provides four options: lithophytes, xerophytes, hydrophytes, and sciophytes. We need to determine which of these categories includes plants that typically have aerenchyma.

3. **Analyzing Each Option**:
- **Lithophytes**: These are plants that grow on rocks. They do not typically have aerenchyma.
- **Xerophytes**: These are plants adapted to dry environments, such as deserts. They also do not possess aerenchyma.
- **Hydrophytes**: These are aquatic plants that thrive in water. They are known to have aerenchyma, which helps them float and survive in their environment.
- **Sciophytes**: These are shade-loving plants that grow in low light conditions. They do not generally have aerenchyma.

4. **Conclusion**: Based on the analysis, the correct answer is hydrophytes, as they are the plants that contain aerenchyma.

**Final Answer**: Aerenchyma is found in hydrophytes.
