Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Photosynthesis is an important process because it harnesses the sun's energy into utilizable forms of energy on earth. Most biological organisms such as animals and fungi are unable to directly use light energy to power biological processes such as active transport, cell division and muscle movement. ATP is used to power these processes. Photosynthesis converts light energy into chemical energy in the form of glucose and then the process of cellular respiration converts energy in glucose to energy in the form of ATP which is ultimately used to power biological processes. The...

As a result, photosynthesis is the crucial source of carbon in the organic molecules found in most organisms. The high oxygen concentration in the atmosphere is derived directly from the light reactions of photosynthesis. Prior to the evolution of photosynthesis on earth, the atmosphere was absent of any oxygen
The rate of photosynthesis is determined by environmental factors. Factors affecting photosynthetic rates include light intensity, water availability, soil nutrient content, concentration of carbon dioxide and temperature. When water availability is reduced, photosynthesis is mainly limited by a decrease in the diffusion of CO2 into the leaf through the stomata. Stomata typically close when atmospheric…
