How flowers make seeds and how pollination helps plants reproduce

Biology - Grade 4-5

Instructions: Read each problem carefully. Show your thinking in the space provided.
  1. 1
    Cutaway flower showing petals, sepals, stamens, and pistil.

    A flower has petals, stamens, pistils, and sepals. Choose two parts and explain what each part does.

  2. 2
    Pollen moving from one flower to another flower's pistil.

    What is pollination?

  3. 3
    A bee carries pollen from one flower to another.

    A bee visits a flower to drink nectar. Pollen sticks to the bee's body. The bee then visits another flower of the same kind. Explain how the bee helps the plant reproduce.

  4. 4
    Bright scented flowers attracting a bee and butterfly.

    Why do many flowers have bright colors or sweet smells?

  5. 5
    Four-stage pollination and seed formation process.

    Put these steps in order: pollen lands on the pistil, a seed forms, pollen is moved by a pollinator, a flower makes pollen.

  6. 6
    Bee pollination and wind pollination shown side by side.

    A student says, 'All plants need bees to reproduce.' Explain why this statement is not correct.

  7. 7
    A seed sprouting with water and sunlight.

    Look at a seed. Name two things a seed needs in order to sprout and begin growing.

  8. 8
    Cutaway seed showing a protective outer coat.

    What is the job of the seed coat?

  9. 9
    Fluffy seeds floating away from a parent plant.

    Some seeds have fluffy parts that help them float through the air. How does this help the plant?

  10. 10
    Fruit with seeds and a bird helping spread seeds.

    A fruit grows around seeds after a flower is pollinated. Explain one way fruit helps seeds.

  11. 11
    Bee, butterfly, and bird visiting flowers as pollinators.

    Match each pollinator to how it helps: bee, butterfly, bird. Write one sentence for each.

  12. 12
    Pollen grains shown beside a larger seed.

    What is the difference between pollen and a seed?

  13. 13
    Wind carrying pollen between small green flowers.

    A plant has small green flowers with no strong smell. It releases a lot of light pollen into the air. What kind of pollination is this plant likely using? Explain your answer.

  14. 14
    Life cycle of a flowering plant from seed to new seeds.

    Draw or describe the life cycle of a flowering plant starting with a seed.

  15. 15
    Seeds spreading away from a parent plant to grow in new spaces.

    Why is seed dispersal important for plant survival?
