Question

A branching system of the plant-bearing flowers is?

• A. Deliquescence
• B. Inflorescence
• C. Placentation
• D. Cauliflory

Answer 1

Answer: (B)

Inflorescence

A. Deliquescence is the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. It occurs when the vapor pressure of the solution that is formed is less than the partial pressure of water vapor in the air.

B. An inflorescence is the arrangement of flowers on the floral axis of the plant. Two major types are - 1. Racemose - the shoot axis continue to grow indefinitely and the flowers are borne in an acropetal succession that is, younger flowers are present towards the apex and the older flowers are present at the base. The example is a radish. 2. Cymose - the main axis terminated into a flower and has limited growth. The flowers are borne in a basipetal order. The example is teak.

C. Placentation is the arrangement of ovules on placenta within the ovary. Ovary bears ovules on a cushion-like structure called placenta. It is of five types - marginal, axile, parietal, free central and basal.

D. Cauliflory is a botanical term referring to plants that flower and fruit from their main stems or woody trunks rather than from new growth and shoots. This can allow trees to be pollinated or have their seeds dispersed by animals which cannot climb or fly.

So, the correct answer is 'Inflorescence'.
