Question
Plants get carbon dioxide from the:
- Soil
- Sand
- Leaves
- Air
Hint:
Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.
The correct answer is: Air
- During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
- Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
- This transforms the water into oxygen and the carbon dioxide into glucose.
