Cell transport

movement of molecules through a membrane from high concentration to low concentration

• diffusion

• facilitated diffusion

• osmosis

a solution where the concentration of solutes is lower OUTSIDE the cell than inside the cell

• isotonic

• hypotonic

• hypertonic

A solution that has the SAME solute concentration on either side of the membrane

• isotonic

• hypotonic

• hypertonic

the movement of ions and other substances across cell membranes WITHOUT the need for energy

• endocytosis

• exocytosis

• active transport

• passive transport

a process where a cell's membrane folds inward to bring materials into the cell

• exocytosis

• active transport

• endocytosis

• passive transport

a solution where the concentration of solutes is greater OUTSIDE the cell then inside

• hypertonic

• hypotonic

• isotonic

the release of material, within vesicles, by fusing with the cell membrane

• passive transport

• endocytosis

• active transport

• exocytosis

the use of ENERGY to move substances across a membrane from low to high concentration

• active transport

• endocytosis

• passive transport

• exocytosis

a type of passive transport that occurs when molecules diffuse across a membrane THROUGH TRANSPORT PROTEINS

• diffusion

• facilitated diffusion

• osmosis

a substance passing through a membrane without the aid of a membrane protein

• diffusion
