Plants undergo a reaction called photosynthesis to turn the energy from the  polesSunMoonsoil into food. In this  additionsubstitutionendothermicexothermic reaction, carbon dioxide and  waterethanolDNAlactic acid are converted to glucose and oxygen using light energy absorbed by the  chloroplastscytoplasmcell wallribosomes.

Many factors influence the rate of photosynthesis. Light intensity varies with the  inverse squaredirect linearinverse lineardirect 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  limiting factordominant factorstalling factorrestricting factor for photosynthesis, especially since light intensity is often correlated with temperature. A  highlowmoderateboiling temperature decreases the rate of photosynthesis because it means that particles have less  kineticpotentialsoundchemical energy and so reactions happen more slowly. The amount of  carbon dioxidewaterstarchmethane and chlorophyll available also influences the rate. Many of these factors can be controlled in  treehouseskitchensgardensgreenhouses to ensure that plants have the optimum conditions for photosynthesis and growth.

The glucose that photosynthesis produces can be used in a variety of ways in the plant. It can be stored directly as  glycogencellulosestarchchlorophyll, or used to produce fats or oils which can also be stored for later use. Much of the glucose is used directly in  respirationaccommodationtranscriptionreproduction, and some may also be used to produce various compounds such as cellulose for  cell membranescell wallsmitochondriavacuoles or  fatty acidscarbonatesamino acidsDNA for protein synthesis. This last process also requires nitrate ions absorbed by the  phloemrootsxylemleaves.
