CO2 decreases over time. 0.07M NaHCO3 The.07M NaHCO3 test produces a line which is steeper than all the previous curves. The experiment could have been carried out with higher NaHCO3 to see if increasing the concentration would increase the rate of photosynthesis, or if a concentration.1M NaHCO3 produces the maximum rate of photosynthetic reaction. Molarity of NaHCO3 Light Intensity 1/d (m).00 (Distilled water).01.02.05.07. I predict that if the light intensity increases the rate of the reaction will increase at a proportional rate until a certain level is reached, the rate of increases will then go down. I am planning to use the following method for my experiment. It is possible that it had been left here for a while which caused the lamp to heat the elodea. I will be changing the levels of light and CO2 and then measuring the photosynthetic rate. From these recorded times I will work out the rate of the reaction using the following equation.
The lamp should be at the same height for umd supplemental essay each experiment. It helped me get an A grade for biology many years ago. Introduction, this is a A-level biology project. You have been warned. It is used to make the organic products of photosynthesis. They therefore have no stomata and absorb all their CO2 by diffusion through the leaves.
