Photosynthesis converts light energy into chemical energy by making glucose from carbon dioxide and water.
Photosynthesis is the process by which green plants (and other photosynthetic organisms) make their own food using sunlight. In plant cells, chlorophyll in chloroplasts captures light energy and uses it to convert carbon dioxide and water into glucose (a sugar used for energy and growth). During this process, oxygen is released as a waste product. Overall, photosynthesis uses light energy to drive chemical reactions. In the light-dependent reactions, sunlight splits water (photolysis), producing oxygen, energized electrons, and ATP/NADPH. In the light-independent reactions (Calvin cycle), carbon dioxide is used along with ATP and NADPH to build glucose. The glucose can be used immediately in respiration to release energy, stored as starch, or converted into other compounds for growth and reproduction.
Photosynthesis converts light energy into chemical energy by making glucose from carbon dioxide and water.
Oxygen is produced during photosynthesis when water is split, and it diffuses out of the plant.
Photosynthesis has two main stages: light-dependent reactions (need light) and light-independent reactions (use ATP and NADPH to build glucose).
A green pigment in chloroplasts that absorbs light energy for photosynthesis.
A sugar produced by photosynthesis that is used for respiration and for building other molecules.
Small openings in leaves that allow carbon dioxide to enter by diffusion.
The light-driven splitting of water molecules during the light-dependent reactions.
A molecule that stores usable energy and is produced during the light-dependent reactions to power later steps.
An energy-carrying molecule formed in the light-dependent reactions that helps drive glucose production in the Calvin cycle.
The light-independent set of reactions that uses carbon dioxide, ATP, and NADPH to build glucose.
