Question
- A. To promote flowering
- B. To increase fruit size
- C. To control weed growth
- D. To enhance seed germination
Answer
The correct option is To increase fruit size. This answer is correct because it matches the approved learning objective to describe (HT only) the use of gibberellins to increase fruit size in the subtopic Use of plant hormones (HT only).
Explanation
The correct option is To increase fruit size. To increase fruit size is correct because it directly supports the approved learning objective to describe (HT only) the use of gibberellins to increase fruit size. 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 Gibberellins' Role
Students often confuse gibberellins with auxins and incorrectly state that auxins are responsible for increasing fruit size.
Students should remember that gibberellins specifically promote fruit size increase, while auxins have different roles such as promoting cell elongation and root development.
