1AnswerD·
Concept: This question tests your knowledge of phyllotaxy, which is the pattern of arrangement of leaves on the stem or branch.
Why (D) Alstonia is correct: In whorled phyllotaxy, more than two leaves arise at each node and form a whorl or circle. Alstonia (also known as Devil's tree or Saptaparni) exhibits this type of leaf arrangement.
Why other options are wrong:
- (A) Calotropis: Shows opposite phyllotaxy, where two leaves arise at each node opposite to each other.
- (B) Mustard: Shows alternate phyllotaxy, where a single leaf arises at each node in an alternate manner.
- (C) China rose: Shows alternate phyllotaxy, similar to mustard.
NEET Tip: Remember common examples for each type of phyllotaxy: Alternate (China rose, Mustard, Sunflower), Opposite (Calotropis, Guava), Whorled (Alstonia).
Correct Answer: (D)
Alstonia.
