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.
Investigating the effect of light intensity on photosynthesis Prediction As the light intensity increases so will the rate of photosynthesis will increases also. This is because the more if light hit's the leaf more electrons are knocked out of the chlorophyll.nvestigating the effect of light intensity on photosynthesis Prediction As the light intensity increases so will the rate of photosynthesis will increases also.
