Question

In cymose inflorescence, the main axis________.
a. Bears a solitary flower
b. Has unlimited growth but lateral branches end in flowers
c. Terminates in a flower
d. Has unlimited growth

Answer 1

Hint: The cymose inflorescence is the type of inflorescence in which a flower is present at the apex of the flower axis. The flower growth is limited. The flowers have centrifugal arrangement. In racemose inflorescence, the main axis grows continuously.

Complete answer:
The inflorescence is the flower arrangement on the flower axis. It is of two types: Racemose and Cymose.
In the Cymose type of inflorescence, the flowers are attached to the main axis and it does not grow continuously. These are borne in a basic order. The main axis has definite growth and terminates in a flower. The peduncle shows sympodial or multipodial growth. The basipetal succession consists of flowers and arrange in centrifugal manner. The older flower is present terminally and the younger ones at the base. The flowers are more commonly arranged and the first flower is at the tip of the peduncle. Flowers bloom at regular intervals and the number of flowers are definite. Flowers protect the newly formed fruits.
From the above information we have found that the main axis in cymose inflorescence terminates in a flower.

Hence, the correct answer is option (C).

Note: The cymose inflorescence is four types: Monochasial cyme, dichasial cyme, polychasial cyme, and cymose Capitulum. Monochasial cyme is also known as uniparous cyme. The main axis terminates in flower and it produces one lateral branch from the base and terminates into flower. Dichasial cyme is called a biparous cyme and polychasial cyme is called a multiparous cyme.
