Plants Parts and Needs — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The roots of a plant grow under the ground.
Roots stay underground where they drink water and hold the plant tight.
2. A flower can grow into a fruit with seeds inside.
Flowers turn into fruit, and the seeds inside can sprout into new plants later.
3. Leaves are usually the color green.
Leaves are green because they hold a special part that helps catch sunlight.
4. A baby plant first pokes up as a tiny sprout.
After a seed soaks up water, a small sprout pushes up through the soil.
5. Plants need light from the sun to make food.
Sunlight gives plants the energy they need to make food inside their leaves.
6. Plants take in gases from the air to grow.
Plants breathe in gases from the air and use them to make food and grow.
7. Without water, a plant will wilt.
Without water, a plant cannot stay stiff, so its stem and leaves bend down.
8. Trees are very big plants with strong stems.
Trees are large plants with thick wooden stems called trunks that grow tall.
9. Bees help flowers make seeds for new plants.
Bees move pollen between flowers, which helps the flowers form seeds for next year.
