Question

A plant cell has a solute potential of -2 and a pressure potential of 0. What is the total water potential of the cell?

1) -2
2) 0
3) -2 + 0
4) -2 - 0

Answer 1

The total water potential of the plant cell is -2.

Step-by-step explanation:

The total water potential of a plant cell is the sum of the solute potential (Ys) and the pressure potential (Yp). In this case, the solute potential is -2 and the pressure potential is 0. To find the total water potential, we simply add these two values together:

Total water potential = Ys + Yp

Total water potential = -2 + 0

Therefore, the total water potential of the cell is -2.
