Paper Summary:

The paper focuses on an experiment that measures the absorption rate of photosynthetic cells under two variation in the light properties: intensity and wavelength. The paper describes the methods used and explains the results that show the light conditions in which plants and other photosynthetic organisms would be most efficient in the production of photosynthesis. The paper also notes the limitations of this experiment and the options for future research.

From the Paper:

"Photosynthesis is the intricate process in certain organisms in which carbon dioxide and water is turned to oxygen and carbohydrates using the energy from sunlight. This sunlight is captured by photosystems within the chloroplast of the organism and supplies energy to drive the reaction. This experiment will measure the absorption rate of these photosynthetic cells under two variation in the light properties: intensity and wavelength. Eight different intensities and four different wavelengths will be systemically induced on cuvettes containing an artificial electron acceptor and chloroplast removed from spinach leaves. The absorbance levels will be recorded every 2 minutes for 16 minutes using a spectrophotometer and allow for photosynthetic rates to be calculated."
