Which of the following is NOT a feature of insect pollinated plant?

The correct answer is Option (1) → Light and non sticky pollen grains

Option (1) Light and non sticky pollen grains — Not a feature of insect pollinated plants. Light, non-sticky pollen suits wind pollination, as wind currents can carry it. Insect-pollinated flowers have sticky pollen that clings to the insect’s body.

Option (2) Flowers are large and colourful — A feature of insect pollinated plants. Large, bright flowers attract insects by sight. Small flowers are grouped into an inflorescence to stand out.

Option (3) Presence of nectar — A feature of insect pollinated plants. Nectar is the reward that brings insects back to the flower.

Option (4) Flower with fragrance — A feature of insect pollinated plants. Fragrance attracts insects by smell, just as bright colour attracts them by sight. The book lists fragrance among the features of most insect-pollinated flowers, with size, colour and nectar.

NCERT Extract:
Pollination – “… Majority of insect-pollinated flowers are large, colourful, fragrant and rich in nectar. When the flowers are small, a number of flowers are clustered into an inflorescence to make them conspicuous.”
Pollination – “… Wind pollination also requires that the pollen grains are light and non-sticky so that they can be transported in wind currents.”
