In Class 11 Biology (Morphology of Flowering Plants), the arrangement of flowers on the floral axis is called 'Inflorescence'. There are two main types: Racemose and Cymose. Let's study the Racemose Inflorescence.
Inflorescence: The arrangement of flowers on a plant stem.
Racemose Main Axis: Never stops growing.
Acropetal Order: Old flowers at the base, new buds at the tip.
In a Racemose inflorescence, the main axis (the central stem) continues to grow endlessly and does not terminate into a flower. Instead, the flowers are born laterally (on the sides) of the growing stem.
Acropetal Succession:
Racemose inflorescence is an arrangement where the main stem continues to grow endlessly, and flowers grow on the sides in an acropetal succession (older flowers at the bottom, younger buds at the top).
