Unless otherwise noted in the margin the value of each question is 4 points. Water moves to the tissue or region where the water potential is the lowest.
Advantage is that light induces potassium and water uptake, which causes the cell to swell.
It is easier to see swelling in a protoplast than in a cell with a wall. Briefly describe these tests. Fail -safe systems in signal transduction are alternate pathways by which an input signal can induce its physiological response. A staining technique that precipitates calcium in place was used to visualize calcium distribution. The increased calcium in the walls of cells on the top side could help mediate the decreased growth rate observed in these cells as a result of the gravitropic stimulus.
