When organisms like cyanobacteria, algae, and primarily green plants use the energy from light and turn this energy into carbon dioxide, or water into oxygen and sugar, this process is called photosynthesis. The equation for photosynthesis is 6C02 +6H20+light energyв†’ C6H12O6 + 6O2 (Newton, 2019). The sugar created is stored in the starch. Starch is then used as fuel for plants, these are heterotrophs and autotrophs (Newton, 2019). In photosynthesis, there are two stages that are light-dependent. Light-dependent means that these stages convert light into useable, chemical energy.
One of these stages is called the Calvin cycle.
During the Calvin cycle, NADPH and ATP are used as a source of energy to make sugar from CO2 without the need for light (Helminstine, 2019). The speed at which photosynthesis occurs depends on the crucial factors, the light intensity being the most influential, water, temperature, and the concentration of carbon dioxide. A faster rate of photosynthesis means that key components are also at a high capacity.
Like everything in science, there are experiments that can be performed to test the effect of each factor listed on the rate of photosynthesis. In the experiment conducted the effect of light intensity was measured. If the distance from the light source is shorter than another that is father, then the rate of photosynthesis will be higher for the shorter distance.
