1AnswerC·
Concept: This question tests your knowledge of phyllotaxy, which is the pattern of arrangement of leaves on the stem or branch.
Why (C) is correct: In opposite phyllotaxy, two leaves arise at each node, opposite to each other. This arrangement is characteristic of plants like Calotropis and guava.
Why other options are wrong:
- (A) China rose: Exhibits alternate phyllotaxy, where a single leaf arises at each node in an alternating manner.
- (B) Sunflower: Also exhibits alternate phyllotaxy.
- (D) Alstonia: Shows whorled phyllotaxy, where more than two leaves arise at a node and form a whorl.
NEET Tip: Remember common examples for each type of phyllotaxy. For opposite, think 'Guava and Calotropis are opposite'.
Correct Answer: (C)
Calotropis.
