Unformatted text preview: 2+ channels. 1.6.2 When Ca 2+ in the cytosol increases, the Ca 2+ directly opens Cl- channels. Cl- leaves the cell. 1.6.3 Change in membrane potential opens K + channels and K + leaves the cell. 1.6.4 Water potential increases and water follows the KCl out of the cell by osmosis. 1.6.5 The guard cells shrink and the stoma closes. graphing experimental results 1.7 Experimental evidence involves quantitative variables or categorical variables 1.8 The treatment (independent variable) goes on the x axis of a graph and the response (dependent variable) goes on the y axis. 1.9 The appropriate graph is determined by type of variable. Treatment variables are often categorical. BIOL13100 Assignments – read Chapter 39 – Plant sensory systems FINISH Problem Set 4. Expect a pop quiz on graphing soon!
