Summary Introduction
Introduction: Property of water that determines the way it will flow, which depends on the concentration of solutes in water and pressure being exerted on water, is known as water potential. If the concentration of a medium surrounding the cell is higher than the inside, the cell water will move toward the cell.

Explain what would happen if a plant cell was placed in a hypotonic environment and why (be sure to include solute concentrations, water movement and turgor pressure in your explanation)?
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).
Suppose that a scientist exposes a leaf to CO2 labeled with radioactivecarbon-14, which is incorporated into organic compounds inphotosynthetic cells. At various times after exposure, the scientist candetermine the location of the radioactive carbon in the plant. In whattissues would you expect to find the radioactive material immediatelyafter exposure to the labeled carbon? What about during transport?When transport is complete, will the radioactive material be in plantparts above the leaf, below the leaf, or both?
