During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) 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
- Sweet Secret - Education
Calvin shone light on the lollipop and used a radioactive form of carbon called carbon-14 to trace the path that carbon took through the algae’s chloroplast, the part of the cell where photosynthesis occurs By this method, he discovered the steps plants use to make sugar out of carbon dioxide
- Photosynthesis - Education | National Geographic Society
Photosynthesis Autotrophs are organisms that produce their own food They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel
- Chlorophyll - Education | National Geographic Society

- DCPS: 7th Grade Science - National Geographic Society
makes food is called photosynthesis During photosynthesis, leaves use energy from sunlight to combine water and carbon dioxide This reaction, which takes place inside cells called chloroplasts, creates sugar and oxygen The sugar provides energy so the tree can live ENGAGE Encourage students to flip through the articles and
