Osmosis & Diffusion

Osmosis is the diffusion of (a)   through a thin membrane.

Diffusion is the movement of molecules from an area of ________ concentration to an area of ______ concentration

• high, low

• low, high

Passive transport is the movement of molecules across a membrane that does NOT require (a)   .

Active Transport is the movement of molecules across a membrane that DOES require energy.

• True

• False

HYPERtonic solutions: cause the cell to (a)   water because there's HIGER level of solute outside of the cell

Answer explanation

HYPER = high energy. HYPERTONIC = high levels of solute outside of the cell.

HypotOnic solution: less solute (a)   of the cell. Causing the cell to grOw

Answer explanation

HypOtonic = grOw
