Inflorescence

The term inflorescence comes under the method morphology of flowering plants. The Morphology of flowering plants is the study of different parts of the plants, which includes the leaves, flowers, fruits, and stems. In a plant, the flowers either grow individually or in a set of groups, and the groups of flowers are referred to as inflorescence.

 Inflorescence

Inflorescence can also be referred to as the reproductive part of a plant that contains a group of flowers. It is responsible for the positioning of flowers on the floral axis and it is divided into two categories: racemose inflorescence and cymose inflorescence. In the racemose inflorescence, the main axis keeps on growing and the flower develops itself in an acropetal pattern while in the cymose inflorescence the termination of the main axis takes place and the flower grows in a basipetal pattern.
