Match List-I with List-II regarding the types of phyllotaxy and their examples. List-I (Phyllotaxy) List-II (Examples) (A) Alternate (I) Guava (B) Opposite (II) Alstonia (C) Whorled (III) Pea (IV) Sunflower Choose the correct answer from the options given below:
Options
- A(A)-(IV), (B)-(II), (C)-(I)
- B(A)-(IV), (B)-(I), (C)-(II)
- C(A)-(I), (B)-(IV), (C)-(II)
- D(A)-(III), (B)-(I), (C)-(II)
Correct answer
B. (A)-(IV), (B)-(I), (C)-(II)
Step-by-step solution
Phyllotaxy is the pattern of arrangement of leaves on the stem or branch. (A) Alternate phyllotaxy: A single leaf arises at each node in an alternate manner. Examples given in NCERT include sunflower, mustard, and China rose. Therefore, (A) matches with (IV). (B) Opposite phyllotaxy: A pair of leaves arise at each node and lie opposite to each other. Examples include guava and Calotropis. Therefore, (B) matches with (I). (C) Whorled phyllotaxy: More than two leaves arise at a node and form a whorl. An example is Al
