Question
- A. Controlling flowering time
- B. Promoting root formation in cuttings
- C. Enhancing fruit size
- D. Delaying seed germination
Answer
The correct option is Promoting root formation in cuttings. This answer is correct because it matches the approved learning objective to describe (HT only) the use of auxins in tissue culture in the subtopic Use of plant hormones (HT only).
Explanation
The correct option is Promoting root formation in cuttings. Promoting root formation in cuttings is correct because it directly supports the approved learning objective to describe (HT only) the use of auxins in tissue culture. This belongs to the subtopic Use of plant hormones (HT only) within Plant hormones (biology only), so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Use of plant hormones (HT only).
Common mistake
Misunderstanding Auxins in Tissue Culture
Students often confuse the role of auxins in tissue culture with their role in other plant processes, such as growth direction.
Focus on the specific function of auxins in tissue culture, which is to promote cell division and growth of plant tissues in a controlled environment.
