Photosynthesis in spinach leaves and respiration in beans abstract using spinach leaves, we modeled the rate of photosynthesis in controlled environments. The rate of photosynthesis is dependent on many factors, with photosynthetic activity measured using dcpip and a spectrophotometer at 605nm. The mixtures of dcpip the cuvettes were tested individually at different wavelengths and intensities to find the optimal rate of photosynthesis by using a. Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature if you plot the rate of photosynthesis against. The rate of photosynthesis can be measured by the rate at which this dye is using dcpip to determine the concentration of ascorbic acid or vitamin c in.
