  1. Key points: Many organisms make their own food through photosynthesis. Plants, algae, and some unicellular organisms do photosynthesis. Photosynthesis is powered by energy from sunlight. This energy is used to rearrange atoms in carbon dioxide and water to make oxygen and sugars. Carbon dioxide and water are inputs of photosynthesis.

  2. Jul 17, 2016 · 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.

  3. Mar 24, 2024 · Photosynthesis, a pivotal biochemical process, encompasses a series of reactions that convert light energy into chemical energy. The light-dependent reactions, as the name suggests, are contingent on the presence of light and primarily transpire within the thylakoid membranes of chloroplasts.

  4. Feb 14, 2024 · Through aerobic cellular respiration, organisms break down sugars to produce usable energy in the form of ATP. This process consumes gaseous oxygen and releases carbon dioxide and water. There are four steps: glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation.

  5. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by...

  6. May 6, 2024 · 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.
