Question
- A. They are only involved in root growth.
- B. They are important for flowering.
- C. They only affect fruit ripening.
- D. They have no role in seed germination.
Answer
The correct option is They are important for flowering.. This answer is correct because it matches the approved learning objective to explain (HT only) that gibberellins are important in initiating seed germination in the subtopic Control and coordination.
Explanation
The correct option is They are important for flowering.. They are important for flowering. is correct because it directly supports the approved learning objective to explain (HT only) that gibberellins are important in initiating seed germination. This belongs to the subtopic Control and coordination 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 Control and coordination.
Common mistake
Misunderstanding Gibberellins' Role
Students often confuse gibberellins with other hormones and fail to specify their unique role in initiating seed germination.
Focus on the specific function of gibberellins in the germination process, highlighting how they stimulate the production of enzymes that break down food reserves in seeds.
