Insect-pollinated flowers produce a strong, often pleasant, fragrance (scent) to attract insects, which then act as pollinators.

A. large anthers: Large, exposed, pendulous anthers are characteristic of wind-pollinated flowers to easily release pollen into the air. In insect-pollinated flowers, anthers are usually smaller and positioned inside the flower so the insect brushes against them.

B. absence of nectar: Insect-pollinated flowers typically produce nectar as a sugary reward to attract insects and encourage them to visit.

D. scentless flowers: Scentless flowers are usually characteristic of wind-pollinated flowers, as they do not need to attract insects for pollination.
