Question

Branching system of the plant bearing flowers is?
A) Deliquescence
B) Inflorescence
C) Placentation
D) Cauliflory

Answer 1

Branching in angiosperms possibly dichotomous or axillary. In dichotomous branching, the branches form as a result of the same division of a terminal bud that is a bud formed at the apex of a stem into two equal branches that are not resultant from the axillary.

Complete answer:
Branches are the comparable members of the stems. The axillary buds expand into branches by the elongation of the internodes accompanied by growth and expansion of the leaves. The method of arrangement of the branches is known as branching.
Types of Branching
There are mainly two types of branching:
(i) Lateral branching
(ii) Dichotomous branching

I. Lateral Branching:
In lateral branching method, the axillary buds are positioned laterally or sideways and they go on producing branches in acropetal order. Lateral branching is again divided into racemose or indefinite and cymose or definite.
II. Dichotomous Branching:
It is a common method of branching which is seen only in lower plants (eg.cryptogams) where the growing point bifurcates or divides into two uniformly vigorous parts. The branches act in the same manner e.g. Lycopodium.
Deliquescence is the method by which a substance absorbs moisture from the atmosphere until it dissolves in the engrossed water and forms a solution. It occurs when the vapor pressure of the solution that is obtained is less than the partial pressure of water vapor in the air.
An inflorescence is the arrangement of flowers on the floral axis of the plant. Two major types of inflorescence include 1. Racemose: the shoot axis persists to grow indefinitely and the flowers are borne in an acropetal series that is younger flowers are present towards the apex and the older flowers are present at the base. The best example is the radish. 2. Cymose: the main axis is terminated into a flower and has restricted growth. The flowers bear in a basipetal order. An example is teak.
Placentation is the arrangement of ovules on the placenta inside the ovary. Ovary bears ovules on a cushion-like structure known as the placenta. It is of five types, which include marginal, axile, parietal, free central, and basal.
Cauliflory is a botanical expression referring to plants that flower and fruit from their main stems or woody trunks relatively than from new growth and shoots. This can permit trees to be pollinated or have their seeds detached by animals that cannot climb or fly.

Hence the correct answer is option (B) inflorescence.

Note: Branches are members of the stems. There are mainly two types of branching methods including the lateral and dichotomous branching method. The inflorescence is the term which is used to denote the arrangement of flowers on the floral axis of the plant.
