Pollination is the first step in plant reproduction. All life on Earth depends on successful pollination to provide food, shelter, and oxygen. Pollination occurs when pollen grains from the male germ cell of the plant reach the female part, or stigma, of the plant. Ninety (90) percent of all flowering plants require pollination.
Pollinators such as bees, birds, bats, and butterflies are crucial in the process of pollination. While in search of nectar, the pollinators rub against the flower parts and transfer pollen. This allows a tiny pollen grain to travel down the stigma and fertilize the egg to form a seed.
There are many different types of pollinator species and they can each carry pollen in different ways. These animals create partnerships with plants to carry out the life-sustaining needs of both groups. Many plants use various techniques to attract pollinators. Some flower petals even have lines or markings that guide the pollinators to the nectar.
