How flowers make seeds and how pollination helps plants reproduce
Biology - Grade 4-5
- 1
A flower has petals, stamens, pistils, and sepals. Choose two parts and explain what each part does.
- 2
What is pollination?
- 3
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
Why do many flowers have bright colors or sweet smells?
- 5
Put these steps in order: pollen lands on the pistil, a seed forms, pollen is moved by a pollinator, a flower makes pollen.
- 6
A student says, 'All plants need bees to reproduce.' Explain why this statement is not correct.
- 7
Look at a seed. Name two things a seed needs in order to sprout and begin growing.
- 8
What is the job of the seed coat?
- 9
Some seeds have fluffy parts that help them float through the air. How does this help the plant?
- 10
A fruit grows around seeds after a flower is pollinated. Explain one way fruit helps seeds.
- 11
Match each pollinator to how it helps: bee, butterfly, bird. Write one sentence for each.
- 12
What is the difference between pollen and a seed?
- 13
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
Draw or describe the life cycle of a flowering plant starting with a seed.
- 15
Why is seed dispersal important for plant survival?
