Question

Potential Energy is 0

5. A plant cell with a Ws = -7.5 bars keeps a constant volume (at equilibrium) when immersed in an
open-beaker solution that has a Ws =
Is = -4 bars. What is the cell's Up?

Answer 1

The water potential of a plant cell can be determined using the formula: Yp = Ys + Yw. Given that the cell's solute potential (Ys) is -7.5 bars and the solution's solute potential (Yw) is -4 bars, the cell's Yp can be calculated as -11.5 bars.

Step-by-step explanation:

The water potential of a plant cell can be determined using the formula: Yp = Ys + Yw.

Given that the cell's solute potential (Ys) is -7.5 bars and the solution's solute potential (Yw) is -4 bars, we can substitute these values into the formula to find the cell's Yp.

Yp = -7.5 bars + (-4 bars)

Yp = -11.5 bars

Therefore, the cell's Yp is -11.5 bars.
