Photosynthesis

 Photosynthesis 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. It would be impossible to overestimate the importance of photosynthesis in … Read more

Factors Affecting Photosynthesis

 Factors affecting Photosynthesis There are three main factors affecting photosynthesis and several corollary factors. The three main are:   Light irradiance and wavelength Carbon dioxide concentration Temperature. Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to … Read more
