Prediction of the osmotic potential of this cell | Homework Help
1. Consider a plant 20 cm tall growing in well watered soil. Ina dark and humid greenhouse, in the miIDle of the night, you measure the turgor pressure of aliving leaf cell of this plant using a probe inserted in the cell. You find that the turgor pressureis 1.9 MPa. Given the current conditions, what is your prediction of the osmotic potential ofthis cell?
2. If you were to study a similar cell (from question 1), undersimilar environmental conditions (night, saturating humidity, turgor pressure = 1.9 MPa), foundat the top of a redwood tree on a misty night in California. How would your prediction of theosmotic potential change if you knew that the cell was located at the top of a 100 m tall tree?Explain the reason for the change in your prediction using the water potentialequation.
