Biology Note – Photosynthesis (Detailed)
πΏ Biology Notes – Photosynthesis (Detailed) π 1. Introduction Photosynthesis is one of the most essential biological processes on Earth. It is the method by which green plants, algae, and certain bacteria use sunlight to synthesize food from carbon dioxide and water. This process not only provides energy for the plant itself but also forms the foundation of the food chain and produces the oxygen we breathe. π 2. Definition Photosynthesis is the process through which autotrophic organisms (like green plants) convert light energy, usually from the sun, into chemical energy in the form of glucose (a type of sugar). This process takes place primarily in the chloroplasts of plant cells. ⚛️ 3. General Equation of Photosynthesis 6CO_2 + 6H_2O + \text{light energy} \xrightarrow{\text{chlorophyll}} C_6H_{12}O_6 + 6O_2 CO₂ (carbon dioxide) comes from the atmosphere. H₂O (water) is absorbed by the roots from the soil. Chlorophyll absorbs sunlight. C₆H₁₂O₆ (glucose) ...
