A phyloGENETIC tree is not the same thing as a taxonomic tree, which is what Cal described. rRNA and molecular studies are used in phylogenetics to determine relations between species.
1 As the light intensity increases, the rate of photosynthesis increases. 2  However, the rate will not increase beyond a certain level of light intensity. 3  At high light intensities the rate becomes constant, even with further increases in light intensity, there are no increases in the rate.
Light Intensity and the Rate of Photosynthesis. Based on the data collected, the distance the lamp was placed from the test tube with the Elodea plant in it did affect the number of bubbles that formed and floated to the top of the test tube.ince the oxygen bubbles are a product of photosynthesis, one can conclude that the more bubbles formed, the more photosynthesis occurred, thus increasing the rate of photosynthesis. Experimental Design. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants.
