What are the two structural differences between an insect-pollinated plant and a wind-pollinated plant?

Insect-pollinated plants typically have brightly colored flowers and strong fragrances to attract pollinators, whereas wind-pollinated plants often have small, inconspicuous flowers that lack scent. Additionally, insect-pollinated plants usually produce sticky pollen to adhere to pollinators, while wind-pollinated plants generate lightweight, abundant pollen that can be easily carried by the wind.
