Bees and pollination

Science · Insects & Minibeasts · conceptual

Bees and pollination: how flowers and insects depend on each other. Bees visit flowers for nectar, pollen sticks to their bodies and transfers to the next flower. Without pollination many plants cannot make seeds or fruit. Why bees matter for the food we eat.

What mastery looks like

  • Describe how pollen moves from one flower to another when a bee visits to collect nectar
  • Explain that many fruits and vegetables depend on bees or other insects for pollination
  • State what would happen to a garden or farm if there were no pollinating insects

Check your understanding

If Bees and pollination saw a bee buzzing around flowers in the garden, could they explain how the bee is helping the plant — and why that matters for the food we eat?
