Question

The flower is important to a plant because it helps in
A. Attracting
B. Production of nectar
C. Pollination
D. All of the above

Answer 1

Hint: Flower is the reproductive entity in the flowering plants. The vital role of the flower is sexual reproduction by providing a system for the junction of sperms with eggs. It is the part which makes the seed and has the important role in expanding the ecosystem.

Complete step-by-step answer:
An ideal flower consists of four parts: Calyx, Corolla, Androecium and Gynoecium.
 

Calyx is the exterior coil of the flower which is of green colour. Bunch of calyxes are called sepals. The primary function of calyx is it shields the internal section from injuries, drying and safeguarding the young buds. Corolla is found below the calyx and are aromatic and colourful. Bunch of Corolla is called petals. The primary function of Corolla. The vital function of Corolla is in the attraction of insects and birds for the transfer of pollen via pollination. It is found in few flowers like lily, that Calyx and Corolla well defined so are called perianth. Androecium is the male element of the flowering plant with the male gametes present. Commonly named as Stamen. It is composed of anther and filaments. Filament holds the anther and anther construct the pollen grains for pollination. Gynoecium is the female element of the flowering plant with the female gametes present. Commonly named as Pistil or Carpel. It is composed of Stigma, Style and Ovary. Stigma is the gluey section where pollen grains are grasp. Style grips the Stigma and is the middle tube and Ovary is the swollen section which contains ovules. Flowers attract the insects and birds so that the pollination can start. The transfer of pollen grain from the male anther to the female stigma is termed as pollination. So that the seeds can be produced effectively. The transfer of pollen grains is done by the Androecium whereas Gynoecium accepts the pollen grains and fusion takes place leading to zygote, embryo and at last a brand new plant or seed is produced.

Therefore the correct Option is D.

Note: Flowers capture the attention of pollinators so that effective pollination takes place which result in the production of a fruit. The nectar is contained within the flower for the migration and reproduction. It is found that the large flowers contain high quantities of nectar.
