can you make the same assumption about the pressure potential of the potato
Added by Manuel M.
Step 1
Pressure potential is a component of water potential that reflects the physical pressure on water in a plant cell. It can be positive (when the cell is turgid) or negative (when the cell is flaccid). Show more…

Do carrots and potatoes have similar water potentials? Suggest a reason for why there might be differences between the two types of plant cells.
Derrick D.
the water potential of a solution is equal to the osmotic potential plus the pressure potential. Since there is no differential pressure acting on the solution, the pressure potential is equal to zero, making the water potential equal to the osmotic potential. If the equilibrium point between the solutions and the potato cylinders indicates the point where the two water potentials are equal, what is the water potential of the potato cells?

You determine the water potential (Ψw) of tissue in a potato to be -0.9 MPa. When you drop this piece of potato into a beaker of water, what will happen? If the osmotic potential of the potato cells was initially -1.5 MPa, and after the potato piece sat in the water for a while, the osmotic potential was still very close to -1.5 MPa, what would the turgor be? Why does water stop moving into the potato at equilibrium?
