osmosis and water potential

• what is meant by osmosis


  this is the diffusion of water from an area of higher water potential to an area of lower water potential across a selectively permeable membrane
• what is meant by osmosis being passive


  it doesn't require ATP
• what is meant by water potential


  this is the tenancy for water to leave a solution by osmosis
• what is the water potential of pure water


  0kpa
• what happens to a waters water potential if a solute is added to the solution


  it will become more negative
• what is meant by solute potential


  it is the lowering of water potential sue to the presence of solute molecules
• what is meant by a hypertonic solution


  this is when the external solution is more electronegative(more permeable ) to the cell
• what is meant by a hypotonic solution


  this is when the external solution is less electronegative(less permeable ) to the cell
• what is the type of solution of the cell when the external is hypertonic


  hypotonic
• what is the type of solution of the cell when the external is hypotonic


  hypertonic
• what is meant by a isotonic solution


  the electronegativity of both solutions are the same
