As an undergraduate research assistant in the lab of the famous Dr. S. Nameerf, your duties involve measuring water potential in experimental soil- plant- atmosphere systems. Assume you make a series of measurements in a system under normal daylight conditions, with stomata open and photosynthesis occurring. Which of the following correctly depicts the trend your measurement data should follow if the cohesion- tension mechanism is operating?
