Water movement occurs because of the transpiration cohesion tension mechanism. Tension is created by the absence of water molecules, pulling a column of water upwards through the plant. Because the water potential of the air surrounding stomata is lower than that of the stomata, water evaporates from leaves in a process known as transpiration. The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration, so our independent variables would be bright light, fan, dark, and misted.
