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

Hypothesis If a show is placed in the tragic because the amount of hundred 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, exculpate out the surgery of aerobic cellular respiration, with the pastime par: C6H12O6 + 6O2 6 carbon dioxide + 6H2O + ATP + Heat Carbon dioxide is a product that is and so(prenominal) 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 leave alone change aerobic cellular respiration, producing CO2, but because in that look on is no light available to it, it cannot bear up under photosynthesis. Subsequently, there go forth be an excess of CO2 because it is not used in photosynthesis. Conversely, the plant that is placed in light will und ergo photosynthesis, due to the presence of light , and will use CO2. hence 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 average out value of HCl used in the titrations for the control beakers (those that contained no plant) was reason: 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 square 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 motive to get a full essay, order it on our website: BestEssayCheap.com
