Thursday: Pollen on the Move

A bee lands on a purple flower by the park bench. Its back legs are dusted with yellow.

"It is wearing yellow pants!" says Rocket. Raven watches it crawl deep into the flower.

"That yellow dust is pollen," she says. "It is sticking to the fuzzy hairs."

Nova hovers at a safe distance. "Watch where the bee goes next," she says.

The bee lifts off and lands on another purple flower. Rocket gasps. "It is delivering mail!"

What pollen is for

Flowers are not just pretty. A flower is the part of a plant that makes seeds.

Inside most flowers there is a fine powder called pollen.

For a plant to make seeds, pollen must move from one flower part to another.

Often it must move from one flower to a different flower of the same kind.

Pollen cannot walk or fly on its own. Something has to carry it.

Wind carries pollen for some plants, like grasses and many trees.

Animals carry pollen for many others. Those animals are called pollinators.

Who are the pollinators?

Bees are famous pollinators. Butterflies, moths, beetles and flies pollinate too.

Some birds and bats visit flowers and carry pollen as well.

Pollinators do not know they are helping. They visit flowers for food.

Many flowers make a sweet liquid called nectar. Pollinators drink it.

While a bee drinks, pollen sticks to its fuzzy body.

At the next flower, some of that pollen rubs off. The flower is pollinated.

Now the plant can make seeds. Many fruits grow from pollinated flowers.

POLLINATION CHECK
  • Read the question.
  • Tap your answer.
What is pollen?
Why does a bee visit a flower?
What can a plant make after its flower is pollinated?
Which of these also carries pollen for some plants?
PUT POLLINATION IN ORDER
  • ?A bee lands on a flower to drink nectar.
  • ?Pollen sticks to the bee.
  • ?The bee flies to another flower of the same kind.
  • ?Pollen rubs off onto the new flower.
  • ?The plant can now make seeds.
WHY THIS EXERCISELand, pick up pollen, fly, drop pollen, make seeds. That is pollination.
StatementTrue or false?
Pollinators visit flowers because they want to help plants.?
Nectar is a sweet liquid some flowers make.?
Only bees can pollinate flowers.?
Pollen is needed for a plant to make seeds.?
WHY THIS EXERCISEAnimals visit for nectar and pollen. Bees, butterflies, moths, beetles, flies, birds and bats all pollinate.
An animal that carries pollen between flowers is a ____.
The sweet liquid that flowers make is called ____.
Try it
Find one flower outside or in a window box. Look very closely without touching it.
Can you see fine powder inside? Can you see bright petals?
Stand still for three minutes. Does any visitor come?
Safety first
Watch bees from a few steps back. Never touch or swat at one.
If a bee flies near you, stay calm and walk away slowly.
Do not pick or taste any plant. Stay with your grown-up and wash your hands after.
Draw a flower with petals, pollen and a pollinator landing on it. Label each part.

Sweet work, explorer! Tomorrow we get ready for a real flower watch.
