Question

Acropetal succession is seen in ______ inflorescence.
A. Reticulate
B. Solitary
C. Cymose
D. Racemose

Answer 1

Hint: Inflorescence is the pattern in which flowers are arranged on the plant and it is found to be different depending upon the type of plant species.

Complete answer:
The arrangement of flowers occurs in different manner in all the plants. The racemose inflorescence is the one in which the main axis of the plant continues to grow and does not end in a flower. The racemose inflorescence is characterized by acropetal succession which means that the newly developing and young buds and flowers are arranged at the top and the older buds and flowers are found to be present at the bottom of the plant.

Flower is that part of the plant which can be called as modified shoot as the apical meristem of the shoot changes into the floral meristem. In this modification, internodes do not get elongated whereas the axis of the shoot gets condensed. The apex is known to form different types of floral appendages in lateral manner at the nodes present successively in place of forming leaves. The manner in which these developing flowers arranged themselves is known as inflorescence. On the basis of whether apex is continuously growing or getting converted into the flower, inflorescence is of two types- racemose and cymose.

So, the correct answer is (D).

Note: The opposite of acropetal succession is basipetal succession in which the older flowers are found at the top whereas the new ones are present at the bottom of the plant and basipetal succession is the charcterisitic of cymose inflorescence.
