- Photosynthesis - Education | National Geographic Society
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

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
Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts
- Sweet Secret - Education
For centuries, scientists knew that plants could turn carbon dioxide and water into sugar (carbohydrates) using light energy—a process called photosynthesis However, they didn’t know exactly how this was accomplished
- Photosynthesis - Education | National Geographic Society
Learn about the process that plants, algae, and some bacteria use to make their own food and the oxygen we breathe
- Definitions in the Field: Photosynthesis - Education
Did you know that most of the oxygen we breathe comes from tiny plants in the ocean? They make it using a process called photosynthesis National Geographic Explorer and oceanographer Branwen Williams explains how plants use sunlight to feed themselves and give us oxygen
- The Carbon Cycle - Education
It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs The movement of carbon from reservoir to reservoir is known as the carbon cycle
- Carbon Sources and Sinks - Education
As plants photosynthesize, they absorb carbon dioxide from the atmosphere When plants die, the carbon goes into the soil, and microbes can release the carbon back into the atmosphere through decomposition Forests are typically carbon sinks, places that absorb more carbon than they release
