• A flower is a modified shoot where the shoot apical meristem changes into a floral meristem.
  • Internodes remain short, and the axis becomes compact.
  • Floral appendages form laterally at successive nodes instead of leaves.
  • A transformed shoot tip into a flower is always solitary.
  • The arrangement of flowers on the floral axis is called inflorescence.
  • Two major inflorescence types are defined based on apex development: racemose and cymose.

-Racemose inflorescence has a growing main axis with lateral flowers in acropetal succession. 

-Cymose inflorescence features a terminal flower and limited main axis growth, with basipetal flower arrangement.
