Question

Flowers showing basipetal succession are observed in
A) Caesalpinia and Clerodendron
B) Jasmine and gold Mohar
C) Gulmohar and Caesalpinia
D) Clerodendron and Jasmine

Answer 1

Hint: Basipetal succession is defined as the floral arrangement on the plants where both new flowers and buds are found at the bottom while the older flowers are present at the top.

Complete answer:
The floral succession can be a racemose, cymose, special type or mixed type. In racemose inflorescence, flowers are arranged in the acropetal succession in which the younger flowers are at the apex and the older flowers are at the base. In cymose inflorescence, flowers are arranged in basipetal succession in which the younger flower is at the base and older flower at the apex.
 Clerodendron and jasmine: Clerodendron flower shows basipetal succession wherein both new flowers and buds are found at the bottom, while the older flowers are present at the top. Jasmine flower shows basipetal succession wherein both the new flowers and buds are found at the bottom while the older flower is present at the top.
A. Caesalpinia and Clerodendron: The Caesalpinia flower exhibits acropetal succession wherein both the new flowers and the buds are present at the top, whereas the older flower is present at the bottom. Clerodendrum flowers show basipetal succession.
B. Jasmine and Gulmohar: Jasmine flowers show basipetal succession wherein both the new flowers and bus are found at the bottom, while the older flower is present at the top. Gulmohar flowers show acropetal succession wherein both the new flowers and buds are present at the top, whereas the older flower is present at the bottom.
C. Gulmohar and Caesalpinia: Gulmohar flower shows acropetal succession wherein both the new flowers and the buds are present at the top, whereas the older flower is present at the bottom. The Caesalpinia flower features acropetal succession.
Hence, the correct answer is option D.

Note: The difference between basipetal and acropetal is that in basipetal the development and maturation for the opening are from the apex to the base in the sequence. Whereas, in acropetal, it is from the base to apex in the sequence.
