The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Trichomes**: - Trichomes are defined as tiny outgrowths from the epidermis of plants. They can vary in size and shape, ranging from small hair-like structures to larger outgrowths like thorns. 2. **Identifying the Location of Trichomes**: - The question asks where trichomes are found in relation to the plant's structure. The options provided include: - Epidermal structure of root - Appendages of pericycle of stem - Epidermal outgrowth of dicot stem - Hypodermal structure of dicot stem 3. **Analyzing Each Option**: - **Epidermal structure of root**: This option is incorrect because trichomes are not typically associated with the root epidermis. - **Appendages of pericycle of stem**: This option is also incorrect as trichomes do not originate from the pericycle. - **Epidermal outgrowth of dicot stem**: This is the correct option. Trichomes are indeed epidermal outgrowths that can be found on the stems of dicot plants. - **Hypodermal structure of dicot stem**: This option is incorrect because trichomes are not located in the hypodermis. 4. **Conclusion**: - Based on the analysis, the correct answer is that trichomes are found as epidermal outgrowths on the dicot stem. ### Final Answer: Trichomes are epidermal outgrowths of dicot stem.
