Question

The flowers of a raceme are arranged?
A. Acropetally
B. Basipetally
C. Centripetally
D. Centrifugally

Answer 1

Raceme are a cluster of flowers, present separately, they are attached with a short stalk that is located at the equal distance from the central stem. Firstly, the flowers that are present on the central base are developed.

Complete answer:

Option B:
Basipetally raceme arrangement is a type of arrangement where the new flowers or new buds arise at the base, and the older ones are at the top. Thus, option [B] is incorrect.

Option C:
Centripetally raceme arrangement is a type of arrangement where the newer flowers or new buds arise at the center of the inflorescence whereas the older ones are at the periphery. Thus, option [C] is incorrect.

Option D:
Centrifugally raceme arrangement is a type of arrangement where the new buds and new flowers arise at the periphery of the inflorescence and the older ones are at the center. Thus, option [D] is incorrect.

Option A:
Acropetally raceme arrangement is a type of arrangement of the plant flowers on the pedicle of the plant in such a way that the new buds or new flowers are present at the apex, whereas the older flowers are present at the base. Their peduncle is bisexual. Therefore, it can be concluded that the flower arrangement of raceme is acropetally.
Hence, the correct answer is option (A).

Note: A racemoid or a raceme is an indeterminate, unbranched type of an inflorescence that bears a pedicellate type of flowers along with the axis. The example of the raceme inflorescence is mango, gulmohar, neem, etc.
