Question

Which of the following parts of cauliflower is used as a vegetable?
A. Terminal bud with immature flower
B. Unripe inflorescence
C. Fruit
D. Swollen stem

Answer 1

Hint: Cauliflower is considered under the category of vegetable. It is an annual plant that grows once a year. There are two types of inflorescence: racemose and cymose inflorescence.

Complete answer:
Cauliflower belongs to the Brassica oleracea family. It is an annual flower that grows once a year. The edible part of the cauliflower is the unripe inflorescence which consists of the cauliflower head and green leaves. The head part of the cauliflower is eaten. The inflorescence is defined as the arrangement of flowers on the floral axis. The inflorescence is of two types-
a. Racemose- in this inflorescence, the main axis grows continuously while the flowers are borne laterally in acropetal succession.
b. Cymose- in this inflorescence, the main axis stops in the flower. The growth is limited. The growth is termed to be in basipetal order.
In inflorescence, the floral apex does different forms of floral appendages at successive nodes rather than at leaves. The flowers are solitary when the shoot tips get converted to flowers. The cauliflower head is composed of a white inflorescence meristem. It is an unripened inflorescence.
So, option B is correct.
On observing other options, Terminal buds with immature flowers are termed to be floral meristems. They are defined to be in the floral axis. Fruits are the conversion of ovaries. Fruits are obtained from ripening ovaries.

Note: A flower is defined to be a modified shoot. Flowers are the converted form of apical meristem to floral meristem. The internodes don't elongate further and the floral axis condenses to become a flower.
