The correct Answer is:
To solve the question regarding the features of trichomes in the shoot system, we will analyze each option provided and determine which are correct. ### Step-by-Step Solution: 1. **Understanding Trichomes**: - Trichomes are epidermal outgrowths found on the surface of plants, particularly on stems and leaves. They can serve various functions including protection, secretion, and reducing water loss. 2. **Analyzing Each Option**: - **(a) Usually unicelled**: This statement is incorrect. Trichomes are typically multicellular, although some can be unicellular. - **(b) Branched or unbranched**: This statement is correct. Trichomes can be either branched or unbranched in structure. - **(c) May be secretory**: This statement is correct. Some trichomes have the ability to secrete substances, such as resins or oils. - **(d) Soft or stiff**: This statement is correct. Trichomes can vary in texture, being either soft or stiff depending on their type and function. - **(e) Helps against transpiration**: This statement is correct. Trichomes can help reduce water loss by creating a barrier that limits transpiration. 3. **Conclusion**: - Based on the analysis, the correct features of trichomes in the shoot system are: - (b) Branched or unbranched - (c) May be secretory - (d) Soft or stiff - (e) Helps against transpiration - The only incorrect statement is (a) Usually unicelled. ### Final Answer: The correct features with respect to trichomes in the shoot system are: - (b) Branched or unbranched - (c) May be secretory - (d) Soft or stiff - (e) Helps against transpiration
