Diffusion And Osmosis

Front 1

Diffusion -

Back 1

movement of substances from areas of high concentration to low

Front 2

osmosis

Back 2

Movement of molecules of a solvent from a region of low concentration to a region of high concentraion through a semi-permeable membrane or

movement of water from a region of high water potential to ra reigon of low water potential through a semi permebale membrane

movement takes place until a state of eqilibrium is reached

Front 3

Equilibrium -

Back 3

when molecules are spread out evenly

Front 4

Isotonic -

Back 4

Isotonic - concentration of solution is equal to that of the cell

Front 5

Hypertonic -

Refer to the diagram in the previous card

Back 5

concentration of solution is greater to that of the cell, water leaves cell, cell shrinks

Front 6

Hypotonic -

Back 6

concentration of solution is less than that of the cell, water enters cell, cell swells

Front 7

Facilitated diffusion -

Back 7

diffusion of substances across the membrane using a transport protein

Front 8

Difference between simple diffusion and facilitated diffusion

Back 8

Front 9

Endocytosis -

Back 9

cell takes in large particles by engulfing them in its membrane

Front 10

Phagocytosis -

Back 10

large solid particles engulfed

Front 11

Pinocytosis -

Back 11

liquid engulfed by the cell

refer to the diagram in the previous card on endocytosis

Front 12

Exocytosis -

Back 12

pushing materials out of the cell, such as waste products
