3.What does the sodium polyacrylate represent in real plants? 4.What process caused the sodium polyacrylate-filled dialysis tubing to become filled withwater? 5.Explain how water potential plays a part in transpiration. Draw a diagram of the path wa-ter takes in this experiment.
6.How does the fan affect the volume of water left in the beaker after one hour? 7.Describe the ways in which plants can adapt to water supply and environmental factors(both structural and physiological). 8.Investigate an experiment that enables the calculation of transpiration rate. Explain thisprocess. Experiment 4: Measuring Transpiration Using a Potometer Data Tables Table 1: Potometer Data Part Initial Volume (mL) Final Volume (mL) Observations Part A 90 mL 90 mL No change Part B 90 mL 90 mL No change
Table 2: Potometer Data Part Environmental Variable Hypothesized Outcome Initial Volume (mL) Final Volume (mL) Observations Part C Natural sunlight No change in volume 90 mL 89 mL Not much change Part D Dark room No change in volume 90 mL 89 mL No much change Post-Lab Questions
