Insect pollination and wind pollination

1. Insect Pollination and Wind Pollination
Many flowers with brightly colored petals and
attractive chemical scents attract insects that act as agents of pollination.
Reproduction in plants without these features, such as significant flowers, is
through wind-pollination. Wind-pollinated plants include grasses.
