Which of the following is a defining characteristic of a cymose inflorescence?

Options

  1. AThe main axis continues to grow indefinitely.
  2. BFlowers are borne in a basipetal succession.
  3. CThe main axis does not terminate in a flower.
  4. DFlowers are arranged laterally in an acropetal order.

Correct answer

B. Flowers are borne in a basipetal succession.

Step-by-step solution

In a cymose inflorescence, the main axis terminates in a flower, which limits its growth. As a result, the older flowers are present at the apex and the younger flowers are borne lower down on the axis. This arrangement of flowers is known as basipetal succession. In contrast, a racemose inflorescence features a main axis that continues to grow indefinitely and does not terminate in a flower, with flowers arranged laterally in an acropetal succession (older flowers at the base, younger flowers at the apex).
