When a solute is mixed, the water potential of the cell

Options

  1. Aincreases
  2. Bdecreases
  3. Cfirst increases and then decreases
  4. Dremains unchanged

Correct answer

B. decreases

Step-by-step solution

Water molecules possess kinetic energy. In liquid and gaseous form they are in random motion that is both rapid and constant. The greater the concentration of water in a system, the greater is its kinetic energy or water potential. If some solute is dissolved in pure water, the solution has fewer free water and the concentration of water decreases, reducing its water potential.
