Anthocyanins are another type of plant pigment that are purple or red. Say you run a chromatography experiment using the same setup as you did in this lab, and you find that anthocyanins do not move from the line of origin. Assuming the solvent traveled the same distance as in your experiment (D in Table 1 above), what is the Rf value of anthocyanin?

- Suppose that a plant cell membrane is permeable with Na*, CI ions and H20, but not with proteins. In addition, it is assumed that 0.05 M Nacl aqueous solution is present outside the cell membrane, and 0.001 M of protein (P) is present inside. The protein is ionized to p, z = 20, and the opposite ion is CI". From this, calculate the theft potential that occurs between the cell membrane and the external solution in equilibrium. Assume that the activity coefficient of all ions is 1.0.arrow_forwardTwo identical plant cell samples of equal mass were taken from the same plant and were prepared for an experiment.
