Plants undergo a reaction called photosynthesis to turn the energy from the  windoceanMoonSun into food. In this  oxidativeendothermicreductiveexothermic reaction, carbon dioxide and  DNAmethanewaterRNA are converted to glucose and oxygen using light energy absorbed by the  ribosomesmitochondriachloroplastsvacuole.

Many factors influence the rate of photosynthesis. Light intensity varies with the  inverse linearinverse squaredirect squareinverse cube law, which states that the amount of light a plant receives decreases with its distance from the light source. This property means that light intensity is often the  reducing factorstalling factorlimiting factorcontrolling factor for photosynthesis, especially since light intensity is often correlated with temperature. A  lowconstanthighfluctuating temperature decreases the rate of photosynthesis because it means that particles have less  electricalmagnetickineticpotential energy and so reactions happen more slowly. The amount of  carbon dioxideoxygenglucosewater and chlorophyll available also influences the rate. Many of these factors can be controlled in  gardenszoosgreenhousesshops to ensure that plants have the optimum conditions for photosynthesis and growth.
