pollinatorsimportant in more ways than you might think

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

Invertebrate Pollinators Bees Wasps Beetles Butterflies Moths Flies

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.

Moth Pollinated Plants Most moths pollinate the plants at night

Vertebrate Pollinators Bats Hummingbirds Lizards

Bat Pollinated Plants Most moths pollinate the plants at night

Hummingbird Pollinated Plants In the continental United States, hummingbirds are key in

wildflower pollination.

Lizard Pollinated Plants Although uncommon, lizards, skinks, and geckos may be

pollinator

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?
