Question

_______ are arranged in an acropetal order.

• A. Only leaves in racemose inflorescence
• B. Flowers in all types of inflorescence
• C. Flowers in cymose inflorescence
• D. Leaves and flowers in racemose inflorescence

Answer 1

The correct option is D Leaves and flowers in racemose inflorescence

Leaves develop at nodes from the shoot apical meristem. Leaves are arranged in an acropetal order which means that the older leaves are at base and newer leaves at apex.

Inflorescence is the arrangement of flowers on the floral axis.
In racemose inflorescence, the flowers develop in acropetal succession, the older flowers at the base and newer flowers at the apex.
In cymose inflorescence, the flowers develop in basipetal succession, the older flowers at the apex and newer flowers at the base.
Hence the correction option would be option d.
