I think that the photosynthesis reaction is a very efficient system. I wonder if there is a way to see if more intense light actually helps the plant grow better, or if just being in sunlight under any intensity yields the same amount of work.© BrainMass Inc. brainmass.com October 24, 2018, 6:19 pm ad1c9bdddf
Normally the light intensity that the plant gets and uses is sufficient to allow its leaves to utilize 5 mg of Carbon di oxide per hour in photosynthesis. This is coupled with the amount of CO2 available as well. But at a certain point of CO2 concentration [that is 5 mg per hour], the rate of photosynthesis does not increase because of the limiting role of CO2.
Since light is one of ...
The solution discusses if there was a more intense photosynthesis reaction would the plant grow faster.
Photosynthesis Reaction Questions
1) Photosynthesis is estimated to produce 339.99999 g (dry weight) of plant matter per square meter, 50% of which is carbon. Calculate the total number of grams of carbon "fixed" each year by 1000 square meters.
2) The photosynthetic reaction can be represented as:
6CO2 + 6H2O -> C6H12O6 + 6O2
Of the glucose produced, 40.0% is used by the plant to fuel respiration; the rest is converted to plant matter. Calculate the total moles of glucose produced annually in our reference 1000 square meter area.
3) Each mole of glucose produced represents the absorption of 2802.999 kJ of solar energy. If the average energy available from the sunlight over an eight-month period is 1.0 kJ/cm2 per day, what percentage of the incident solar energy is converted to chemical energy in our 1000 square meter area?View Full Posting Details
