If the end of a plant shoot is cut and placed in a dye solution, the solution is drawn by the xylem through a normal physiological process that can be further examined through a microscope. The proposed hypothesis for the experiment was that a red dye would have a faster uptake than a blue dye in a carnation, and a diluted dye would have a faster uptake in the carnation than a concentrated dye, and these hypotheses will be tested on a white rose carnation, where the root and the stem are cut to the same length and to speed up the lab they will be cut to a short length. Results: In Figure 1, one can see that at 14 minutes is the original concentration, which is a .01 M Amaranth Red solution, and the point at 21 minutes has a concentration of .001 M of the same solution. From these points, one can see that if all factors were kept constant other than the molar solution....
