Question:

Which of the following statements are correct about pollination?

(A) Wind pollinated flowers are often very colourful.
(B) In many aquatic plants like water lily, the pollination takes place by insects.
(C) Wind pollination is quite common in grasses.
(D) In most of the water pollinated species, pollen grains are protected from wetting by mucilaginous covering.

Choose the correct answer from the options given below:

Options:

(A), (C) and (D) Only

(B), (C) and (D) Only

(A) and (B) Only

(C) and (D) Only

Correct Answer:

(B), (C) and (D) Only

Explanation:

The correct answer is Option (2) → (B), (C) and (D) Only

A. Wind pollinated flowers are neither colorful nor nectar producing as these are the characters for the insect-pollinated flowers.Flowers that rely on insect pollinators often have bright colors, attractive scents, and nectar rewards to attract the insects.

B. Not all aquatic plants use water for pollination. In a majority of aquatic plants such as water hyacinth and water lily, the flowers emerge above the level of water and are pollinated by insects or wind as in most of the land plants.

C. A familiar example of wind pollination is observed in corn, where the tassels represent the stigma and style that wave in the wind to trap pollen grains. Grasses are a common example of plants that rely on wind pollination.

D. In most of the water-pollinated species, pollen grains are protected from wetting by a mucilaginous covering.
