- Consider a plant cell. The value for solute concentration in a plant cell is -0.12 MPa and the turgor pressure is 0.12 MPa. 1- What is the water potential in this plant cell? 2- If this plant cell were placed in a solution with water potential of -0.1 MPa, what would happen to the cell? (Hint: explain where the water goes and what that does to the cell).arrow_forward1) We measured weights before and after soaking a potato in water of different salinities to demonstrate osmosis. There are many other types of membrane transport (as we learned from the Amoeba Sisters!), each with their role in maintaining homeostasis and providing energy, communication, and waste removal for the cell. So why dwell on osmosis? There are some practical bigger- picture things to consider. Choose one of the following scenarios. Describe the scenario. Describe the chain of events terms of tonicity_and movement of water into or out of cells represented by the scenario. Describe the predicted outcomes for the cells/organisms involved.

In addition, it is assumed that 0.05 M Nacl aqueous solution is present outside the cell membrane, and 0.001 M of protein (P) is present inside. The protein is ionized to p, z = 20, and the opposite ion is CI". From this, calculate the theft potential that occurs between the cell membrane and the external solution in equilibrium. Assume that the activity coefficient of all ions is 1.0.arrow_forward
