It also indicated the stem portion of the leaf contained Xanthophyll 1 and Xanthophyll 2. These results can lead to the conclusion that the same pigments, except for chlorophyll, are present in both the green portion of a leaf and a stem. The second test indicated that the green portion of a leaf did not absorb values of 510 nm though 640 nm, which are green wavelengths. Since plants reflect the colors they do not absorb, this data makes sense. It does not have a high absorbance value, meaning that it does not absorb those wavelengths. The second test also indicated the stem portion of the beet (red) did not absorb values between 510 nm through 640 as well as values between 670 and 740 nm. The second set of values are wavelengths of red, which is why the stems are red. The stems reflect the wavelengths they do not absorb, in this case, red. This can lead to the conclusion that both extracts contain the same pigments since they are both not reflecting the same light. As a result, these tests both indicate that Mark was correct since he had stated that both the green portion of a leaf and the stem contain the same pigments other than
