Large, colourful, fragrant flowers with nectar are seen in
Bird pollinated plants
Bat pollinated plants
Wind pollinated plants
Insect pollinated plants
The correct option is (D): Large, colourful, fragrant flowers with nectar are typically seen in insect-pollinated plants.
These characteristics, such as size, color, fragrance, and nectar production, are adaptations of flowers to attract insects like bees, butterflies, and hummingbirds. Insects are effective pollinators because they are attracted to these features and transfer pollen between flowers as they feed on nectar. The bright colors and pleasant fragrances serve as visual and olfactory signals to attract insects, while the nectar acts as a reward for their pollination services.

Pollination is defined as the pre-fertilization event or process, where pollen grains from another are transferred to the stigma of a flower.
Double fertilization is a complex process that involves the fusion of one female gametophyte with two male gametes.
All plants having flowers completely rely on the pollination method for reproduction. There are 2 types of pollination –
