The Effect of the Presence of Light on the Amount of CO2 Produced by a Plant

Hypothesis If a show is placed in the good-for-naught because the amount of carbon copy dioxide produced pass on be higher, versus, if a plant is placed in the light, indeed the amount of carbon dioxide produced leave alone be lower. This is because only organisms, even plants, act out the surgery of aerobic cellular respiration, with the next equation: C6H12O6 + 6O2 6carbonic acid gas + 6H2O + ATP + Heat Carbon dioxide is a product that is thuslyce utilize to fuel photosynthesis, which occurs in all plants. The equation for photosynthesis is as follows: 6CO2 + 12H2O C6H12O6 + 6H2O + 6O2 light Therefore, the plant that is placed in the dark allow change aerobic cellular respiration, producing CO2, but because in that prise is no light available to it, it cannot bear with photosynthesis. Subsequently, there pass on be an excess of CO2 because it is not used in photosynthesis. Conversely, the plant that is placed in light will undergo photos ynthesis, due to the presence of light , and will use CO2. whence the light plants will have less CO2 then the dark plants. Results Beaker substance of CO2 Present (µM of CO2/g/hr) 4 - Light         185.0 5 - Light         93.8 6 - Light         31.9 7 - caliginous         98.0 8 - Dark         23.6 9 - Dark          -44.0 The Effect of the Presence of Light on the Amount of CO2 Produced by a Plant The ordinary value of HCl used in the titrations for the control beakers (those that contained no plant) was calculate: 11.39 mL + 12.36 mL + 11.11 mL = 11.62 mL of HCl used 3 This average was then used in calculations used to muster up the amount of CO2 present in beakers 4 - 9. The following formula was used: µM of CO2/g/hr = Beaker #4: M of CO2/g/hr = [11.39 mL- 9.4 mL... If you pauperization to get a full essay, order it on our website: BestEssay! Cheap.com
