Photosynthesis involves two stages: the light-dependent reactions, which require sunlight and water to produce oxygen, ATP, and NADPH, and the light-independent reactions (or "dark reactions"), which use the products of the light-dependent reactions along with carbon dioxide to produce carbohydrates.

Photosynthesis occurs in two phases: the light-dependent reactions, and the light-independent reactions.

Light-dependent reactions use light energy and water to produce ATP, NADPH, and oxygen. Light-independent reactions then uses ATP, NADPH, and carbon dioxide to create sugar. This process transforms light energy into a usable form, supporting life on Earth.
