Movement In And Out Of A Cell

osmosis is ….

• the active movement of molecules from a region of their lower concentration to a region of their higher concentration.

• the movement of water molecules though a partially permeable membrane from a more concentrated solution to a more dilute concentration.

• particles from a region of lower concentration to a region of higher concentration using energy from respiration.

• the movement of water molecules through a partially permeable membrane from a more dilute to a more concentrated solution
