Trichomes, hairs, stomata etc are included under

Options

A. Ground tissue system
B. Vascular tissue system
C. Epidermal tissue system
D. None

Answer

**Step-by-Step Solution:**

1. **Identify the Components**: The question asks about trichomes, hairs, and stomata. These are structures found on the surface of plants.

2. **Classify the Structures**: Trichomes (plant hairs) and stomata (pores for gas exchange) are both part of the plant's epidermis. They serve various functions, such as protection, reducing water loss, and facilitating gas exchange.

3. **Understand Their Functions**:
- **Trichomes**: These can be unicellular or multicellular and serve various functions, including protection against herbivores and reducing water loss.
- **Stomata**: These are openings that allow for gas exchange (CO2 in, O2 out) and are crucial for photosynthesis and transpiration.

4. **Group the Structures**: Since trichomes, hairs, and stomata are all located on the epidermis of plants and serve protective and functional roles, they can be collectively categorized.

5. **Conclusion**: Therefore, trichomes, hairs, and stomata are included under the category of **epidermal structures** or **epidermal tissues** in plants.
