Pollination Pollination - When pollen is moved within
flowers or carried from flower to flower by pollinating animals, the wind, or water.
About 80% of all plants are pollinated by biotic pollinators

Pollinators An animal that carries pollen from one
flower to another Pollinators get two things by visiting
plants:1. Nectar - Liquid sugar, a high energy
substance2. Pollen – High protein substance
Bees may collect this & feed to their young Other pollinators pick this up unintentionally
in their hair.

Why Plants Need Pollinators The transfer of pollen in and between
flowers of the same species leads to fertilization, and successful seed and fruit production for plants.
Pollination ensures that a plant will produce full-bodied fruit and a full set of viable seeds.

Did you know? At least 1/3 of all the foods you eat are
dependent upon pollinators. This means that millions of plants are
dependent on pollinators to reproduce!

Plant Strategies Attracting pollinators is so important
that plants have adapted strategies to attract pollinators to them: Color Form or shape Scent

Bee Pollinated Plants In the United States, there are over 4,000 species of native
bees.
What a human sees… What a bee sees…

Butterfly Pollinated Plants Butterflies are less efficient than bees at moving pollen
between plants.

wildflower pollination.

Checking Up1. Why are pollinators important to the
survival of plants?2. How do plants ensure pollinators will
visit them?3. What do you think would happen if a
plant was pollinated by only one or two species of pollinators?
