Aerial absorptive roots occur in

Options

A. Epiphytes
B. Mosophytes
C. Hdrophytes
D. Xerophytes.

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of Plants:**
- The question asks about aerial absorptive roots and provides four types of plants: epiphytes, mesophytes, hydrophytes, and xerophytes.
- It is essential to understand what each type of plant is and their respective root systems.

2. **Identifying Epiphytes:**
- Epiphytes are plants that grow on other plants (usually trees) but do not take nutrients from them.
- They have specialized roots known as epiphytic roots that hang freely in the air.

3. **Function of Epiphytic Roots:**
- These roots are adapted to absorb moisture and nutrients directly from the air and rain.
- They contain a special tissue called vellumen, which helps in moisture absorption.

4. **Analyzing Other Plant Types:**
- **Mesophytes:** These plants thrive in environments that are neither too dry nor too wet. Their roots are typically found in the soil.
- **Hydrophytes:** These are aquatic plants that grow in water. Their roots are submerged and not aerial.
- **Xerophytes:** These plants are adapted to arid environments and have roots that are also found in the soil, designed to conserve water.

5. **Conclusion:**
- Since only epiphytes have aerial absorptive roots that hang freely in the air and absorb moisture from the atmosphere, the correct answer to the question is **epiphytes**.

**Final Answer:**
Aerial absorptive roots occur in **epiphytes**.
