- C. It inhibits leaf fall.
- D. It enhances photosynthesis.
Answer
The correct option is It controls cell division and fruit ripening.. This answer is correct because it matches the approved learning objective to explain (HT only) that ethene controls cell division and fruit ripening in the subtopic Control and coordination.
Explanation
The correct option is It controls cell division and fruit ripening.. It controls cell division and fruit ripening. is correct because it directly supports the approved learning objective to explain (HT only) that ethene controls cell division and fruit ripening. 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 Ethene's Role
Students often confuse ethene's role in fruit ripening with its role in other plant processes, such as growth or photosynthesis.
Focus on the specific function of ethene in regulating cell division and the ripening process, and differentiate it from other hormones and their roles.
