Nov 13, 2024 · Photosynthesis is 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.
May 14, 2022 · The heart of photosynthesis as it occurs in most autotrophs consists of two key processes: the removal of hydrogen (H) atoms from water molecules; the reduction of carbon dioxide (CO 2) by these hydrogen atoms to form organic molecules. The second process involves a cyclic series of reactions named (after its discoverer) the Calvin Cycle.
Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen. Leaves contain microscopic cellular organelles known as chloroplasts. Each chloroplast contains a green-coloured pigment called chlorophyll.

The photons in light provide the energy that drives photosynthesis. The chemical formula is the same for the two types of simple sugars produced by photosynthesis: glucose and fructose: C 6 H 12 O 6. The equation that summarizes photosynthesis is: water + carbon dioxide -> oxygen, water, and simple sugars.
Jun 21, 2024 · The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.
Key Points. Light energy splits water and extracts electrons in photosystem II (PSII); then electrons are moved from PSII to cytochrome b6f to photosystem I (PSI) and reduce in energy. Electrons are re-energized in PSI and those high energy electrons reduce NADP + to NADPH.
