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?

- Water will always move from an area of high water potential to low water potential. If you drop a cell with WP = 0 into the water with WP = -0.9, then what will happen to the cell?arrow_forwardImagine a cell with a water potential of –0.1 MPa being placed in a beaker of solution that also has a water potential of –0.1 MPa. Are the two water potentials in equilibrium? Would any water molecules be moving between the cell and the solution? Would there be a net movement of water?

- In conditions of dehydration, plant cells can increase their water retention by regulating the function of some or all of their aquaporins, membrane-bound protein channels that allow water to move through the cell membrane via facilitated diffusion. Which of the following describes a likely mechanism by which aquaporins can be used to regulate the movement of water across the plant cell membrane? A B с D Synthesis of additional aquaporins by the plant cell ribosomes will allow the cell to coun- teract the movement of water out of the cell. Inhibition of ATP hydrolysis will make the aquaporins unable to remove water from the cell and cause more water to remain in the cell. Inactivation of aquaporins will make water molecules unable to move across the plant cell membrane and allow more water to remain in the cell. Inhibition of the plant cell Golgi apparatus will decrease the production rate of vesicles and slow down the exocytosis of water molecules.arrow_forwardIf you place a flaccid plant cell with ΨS = -0.4 MPa in pure water, which of the following will occur?

(the ratio pH9.0/pH 4.0) Hint: pH is measured on a logarithmic scale, consider this in your calculationarrow_forwardSuppose 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_forward
