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.
Rate of photosynthesis Intensity of light Rate of photosynthesis Carbon dioxide concentration. 2 Temperature and rate of photosynthesis Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light in dependent reactions of photosynthesis are dependent on temperature.They are reactions catalysed by enzymes.
