Wednesday: Why Pollinators Visit

Rocket builds a flower out of paper and sets it outside. "Come on, bees!" he calls. Nobody comes.

Raven compares it to a real flower. "What do you notice? What does the real one have that yours does not?"

Nova hovers between them. "Visitors come for a reason," she says. "What might they get from a real flower?"

Rocket gasps. "Food!"

Flower food

Pollinators visit flowers for food.

Nectar is a sugary liquid. It gives pollinators energy to fly.

Pollen gives them proteins, fats, vitamins and minerals.

While an animal feeds, pollen sticks to its body.

At the next flower, some of that pollen rubs off on the stigma.

  • Nectar: sugar for energy
  • Pollen: proteins, fats, vitamins and minerals

  • Read the question.
  • Tap your answer.
What does nectar give a pollinator?
How does pollen get from one flower to the next?

How flowers say "visit me"

Flowers use showy petals, color, shape and size to attract pollinators.

Some flowers also have scents.

Some flowers have nectar guides. These are patterns that point to the nectar.

Some nectar guides show up only in ultraviolet light.

People cannot see ultraviolet light, but bees can.

StatementTrue or false?
Pollinators visit flowers for food.?
Nectar guides help pollinators find the nectar.?
People can see ultraviolet patterns on flowers.?
Pollen gives pollinators proteins and vitamins.?
WHY THIS EXERCISEColor, scent and food bring pollinators, and pollen hitches a ride.

A big job

About 80 percent of all flowering plants rely on animal pollinators.

That means about 8 out of every 10 kinds.

About what percent of flowering plants rely on animal pollinators? Type the number.
WHY THIS EXERCISEAbout 80 percent of flowering plants need animal pollinators.
Try it
Look at your bean plant. Are there any flower buds yet?
Measure the stem and write it in your growth log.
Look at a flower picture. Find lines or spots that could be nectar guides.
Safety first
Touch your plant gently. Wash your hands after.
Never taste nectar, pollen or any flower part.
The sugary liquid in flowers is ____.
Bees can see ____ light.
Design a flower that a pollinator would love. Show its color, shape and nectar guides.

Great reasoning! Tomorrow we match flowers to the pollinators that visit them.
