Question

B. Flowers once in a lifetime
C. Produces only one seed
D. Produces only one fruit

Answer 1

Hint: Flowering plants are also called as angiosperms, and they use sexual mode of reproduction, in plants reproduction mainly revolves around the flower which has both the male and female gametes, and all parts of the flower aid in reproduction, but some of them are sterile.

Complete step by step answer:
-Plants are classified based on the different types of flowers that show their life cycle and fruit formation.
-One of them is monocarpic plants which means these are flowering plants that produce flowers and seeds once In their lifetime.
-These are generally considered as biennial or perennial and very few monocarpic fruits are perennial.
-Monocarpic plants die after the flowering and the fruiting in the plants occurs.
-These plants are short lived and they can live several years before flowering occurs, and some of the examples are rice, wheat and carrot, etc.
-There are other types of plants based on the life cycle that are polycarpic, where these plants produce flowers and fruits many times every year and these plants are perennial.
-Unlike monocarpic plants, polycarpic plants do not die after flowering and fruiting; they are sexually active throughout their life and they can consider them as long lived plants.
-These polycarpic plants produce multiple times due to the presence of meristematic preparation.
So in the question, they asked about the monocarpic so that the correct option is B. Flowers once in a lifetime.

Note: Sometimes Monocarpic plants can be kept alive after flowering, if the flowers are removed as soon as they have finished blooming before seed germination begins, and they can also live if the flower buds are removed before they begin blooming.
