Osmosis

• The partially permeable membrane allows the passage of water but not the dissolved solids.
• The surface area of the membrane can affect the rate of osmosis, with larger surface areas generally allowing for faster osmosis.
• The concentration gradient between the two solutions affects the direction and rate of osmosis.
• Osmosis continues until the water concentration gradient across the membrane reaches equilibrium.
• Grade 9 Definition=

  Osmosis is the movement of water.

  From and area of high water potential to a region of lower water potential...

  Through a partially permeable membrane, until dynamic equilibrium is reached. (no net movement)
