Question

Dichasial cyme is characteristically found in
A. Gossypium
B. Calotropis
C. Alocasia
D. Dianthus

Answer 1

Hint: Inflorescence can be defined as the process of development of the complete flower of a plant that has stems, stalks, bracts, and flowers. Simply we can say it is the process in which the arrangement of flower parts is done in a plant.

Complete answer:
An inflorescence is referred to as a cluster of arranged flowers on a stem that is a collection of the main branch or a complicated arrangement of branches of a plant. Cymose can be defined as the determinate simple inflorescences. One of the main kinds of cymose inflorescence is called cyme. The cyme is referred to as dichasial when two secondary axes are present.
If an inflorescence has two lateral branches that are developed on either side of the terminal lower axis which again forms a branch is known as dichasial cyme. An example includes Dianthus species which is a mostly herbaceous perennial plant and some of the species are low subshrubs that have woody basal stems. The arrangement of the leaves is opposite, simple and mostly linear, and often has strong colours like grey-green to blue-green. The flowers have five petals, with dichasial cyme.
So, the correct answer is option D, i.e., Dianthus.

Note: The other flowers that are mentioned in the question shows the inflorescence –
a. Scorpioid cyme is seen in the case of Gossypium.
b. Spadix inflorescence is seen in Alocais. In this type of inflorescence the stem is fleshy.
