1 Diffusion is the movement of particles from a region of high concentration to a region of low concentration down diffusion gradient. Dif FuSion Steven, Amal & Eza 2011 1

2 Diffusion is the movement of particles from a region of high concentration to a region of low concentration down diffusion gradient. Diffusion takes place when molecules from high concentration region moves to low concentration region without using added energy. Dif FuSion Steven, Amal & Eza 2011 2

3 Diffusion is the movement of particles from a region of high concentration to a region of low concentration down diffusion gradient. Diffusion takes place when molecules from high concentration region moves to low concentration region without using added energy. Isotonic - a solution in which the solute and solvent are equally distributed Hypotonic -a solution which contains more solvent than solute (example: salt solution) Hypertonic -a solution which contains more solute than solvent (example: sports drink) Dif FuSion 3 Types of Solution Steven, Amal & Eza 2011 3

5 Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane. Os MoSiS Steven, Amal & Eza 2011 5

6 Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane. Osmosis takes place when water molecules from high concentration region moves to low concentration region passing through a semi permeable membrane. Os MoSiS Steven, Amal & Eza 2011 6

7 Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane. Osmosis takes place when water molecules from high concentration region moves to low concentration region passing through a semi permeable membrane. Os MoSiS Steven, Amal & Eza 2011 7 A semi permeable membrane allows some molecules to pass through it and prevents other large molecules from crossing through it.

8 Osmosis is the movement of water particles from a region of high concentration to a region of low concentration through a semi permeable membrane. - vegetables are soaked in water to restore its freshness - after half an hour dipping in swimming pools, the hands become wrinkled.
