As a result, the youngest flowers are at the top and the oldest flowers are at the base of the stalk.

What is acropetal order?

Acropetal order is a term that is the modified form of racemose inflorescence. It is the arrangement of plant flowers on the plant's pedicel in the manner in which the new flowers and new buds are at the apex, whereas the relatively older flowers are placed at the base.

What is Basipetal arrangement of flowers?

Basipetal succession is the arrangement of flowers on plant in which new flowers and buds are present at the bottom and the older flowers are present at the top. This type of succession is found in plants like Clerodendrum and Jasmine.

What is acropetal and centripetal succession?

Acropetal succession refers to the arrangement of flowers, where the older flowers are present at the base and younger flowers are present at the apex. In the centripetal succession, the younger flowers are present at the centre and older flowers are present towards the periphery.

What is Apex in plants?

In botany, apex refers to the highest point or vertex of a plant stem or root. The shoot apex is where fresh stems, leaves, and other parts of a plant grow after the old parts fall off or dry up.
