The Effect of Light Exposure on a Plants Stomata MechanismABSTRACTThe experiment focused on measuring the rate of transpiration with reference to the following variables, normal light conditions, continuous light conditions, no light conditions, and half-light / half-dark conditions. The plant subjects were in each controlled environment for 24 hours prior to completing each experiment, and then the transpiration tests were performed. The variables tested concluded continuous light produced the greatest extended stimulation of the stomata; the normal light produced the most consistent with gradual digression stimulation of the stomata; and the no light and half-light/half-dark produced minimal stimulation of the stomata. The continuous light proved the most stimulation, but stressed the plant and exhibited the greatest decrease of transpiration, the normal light proved to be the most consistent display of transpiration with a more controlled rate of digression, and the no light and half-light/half-dark showed minimal rates of transpiration.
