Web4 jul. 2024 · When photons strike the molecules and are absorbed, the electrons of those molecules get excited to a higher energy level. When the light source is removed, the electrons may return to their original states, give off energy as heat or light, or be transferred to other molecules. Visible light is the region of importance in photosynthesis. Web18 uur geleden · Aug. 5, 2024 — Photosynthesis is the natural process plants and algae utilize to capture sunlight and fix carbon dioxide into energy-rich sugars that fuel growth, development, and in the case of ...
Web7 jul. 2024 · The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis ( Figure 1 ). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl). All photosynthetic organisms contain Chl. WebIn plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2), hydrogen ions (H +), and electrons. Most of the removed electrons and hydrogen ions ultimately …
