Photosynthesis – National Geographic Society
15 juil. 2022The process. 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.

Photosynthesis | Definition, Formula, Process, Diagram, Reactants …
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Photosynthesis – Wikipedia
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the hydrogen carrier NADPH and the energy-storage molecule ATP. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.

Explainer: How photosynthesis works – Science News Explores
Photosynthesis is the process of creating sugar and oxygen from carbon dioxide, water and sunlight. It happens through a long series of chemical reactions. But it can be summarized like this: Carbon dioxide, water and light go in. Glucose, water and oxygen come out. (Glucose is a simple sugar.)

How Does Photosynthesis Work? | Sciencing
The photosynthesis process on Earth is responsible for the oxygen that is in the atmosphere. Without plants and other green living things that turn light energy from the sun into chemical nutrients for the plant, releasing oxygen into the atmosphere, life would probably not exist in its form today.

How photosynthesis and its light and dark reactions work
Photosynthesis is crucial for maintaining life on Earth; if it ceased, there would soon be little food or other organic matter on the planet, and most types of organisms would disappear. light reaction of photosynthesis Photosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages.

Intro to photosynthesis (article) | Khan Academy
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy and …

Photosynthesis – Understanding Global Change
Photosynthesizing organisms (plants, algae, and bacteria) provide most of the chemical energy that flows through the biosphere. They also produced most of the biomass that led to the fossil fuels that power much of our modern world. Photosynthesis takes place on land, in the ocean, and in freshwater environments.
