- 5. An insect takes pollen from the stamen to the pistil. The pollen joins an ovule inside the pistil. They make a seed. The petals fall off and the pistil grows into a fruit. The fruit falls on the ground and its seed grows into a new plant. How do plants reproduce?
- 6. Photosynthesis = minerals + water + sunlight + carbon dioxide = food + oxygen Roots absorb minerals and water Leaves absorb sunlight and carbon dioxide How do plants make food?
- 7. How do we classify plants? Trees have a big, woody stem called a trunk. Grasses have flexible green stems. Bushes have woody stems, but they don’t have a trunk. They have branches near the ground.
- 8. How do we classify plants? Deciduous plants lose their leaves in autumn. Evergreen plants always have leaves.
