3.3a: Describe the structures of an insect-pollinated and wind-pollinated flower and explain how each is adapted for pollination.

• Pollination of a flower has to be transfer of pollen grains from the anther to the stigma of the other.
• Pollen is a male plant. These processes are transfer by insect. By the flowers attract the insect.
• If pollen goes trough one plant to another this is call cross-pollination.
• Flowers can attract insects by:
• Signal (colour petal) 
• Scent (detected molecule)
• Value (produce sugar called fructose)
• Pollen it self as a source of protein.
