Flowers that are pollinated by insects typically have bright colors and strong scents to attract insects. The scent of the flower is produced by the nectar, which is a sweet liquid that the insects feed on. The insects are attracted to the scent of the flower, and when they land on the flower to feed on the nectar, they transfer pollen from one flower to another, helping to pollinate the plant.
Wind-pollinated flowers, on the other hand, do not have bright colors or strong scents. They rely on the wind to carry their pollen from one flower to another. The pollen produced by wind-pollinated flowers is light and dry, so it can be easily carried by the wind.
