Velamen tissue in orchids is found in

Options

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

Answer

**Step-by-Step Text Solution:**

1. **Understanding Velamen Tissue**: Velamen tissue is a specialized tissue found in the roots of certain plants, particularly orchids. It is primarily composed of multiple layers of epidermal cells.

2. **Location of Velamen Tissue**: This tissue is specifically found in the aerial roots of orchids. Aerial roots are those that grow above the ground, often used by epiphytic plants to absorb moisture and nutrients from the air.

3. **Function of Velamen Tissue**: The main function of velamen tissue is to protect the plant roots from ultraviolet (UV) radiation. It acts as a barrier, helping to shield the sensitive root tissues from harmful sunlight.

4. **Types of Plants**: The question provides four options: mesophytes, epiphytes, hydrophytes, and xerophytes.
- **Mesophytes**: These are plants that require a moderate amount of water.
- **Hydrophytes**: These are aquatic plants that live in water.
- **Xerophytes**: These are plants adapted to survive in dry environments with limited water.
- **Epiphytes**: These are plants that grow on other plants (like trees) but are not parasitic.

5. **Identifying the Correct Answer**: Since velamen tissue is specifically found in the aerial roots of orchids, which are classified as epiphytes, the correct answer to the question is option B: epiphytes.

**Final Answer**: Velamen tissue in orchids is found in epiphytes.
