Cell Membrane Vocabulary

a solution with a higher solute concentration on the outside of the cell and a lower solute concentration on the inside of the cell. Water will move out of the cell causing the cell to shrink and shrivel.

• Hypertonic Solution

• Hypotonic Solution

solution with lower solute concentration on outside of cell and higher solute concentration on inside of cell. Water will into the cell causing the cell to swell and eventually burst

• Hypertonic Solution

• Hypotonic Solution

NGSS.HS-LS1-3

a solution that has the SAME solute concentration on the outside and inside of the cell. There will be NO NET MOVEMENT of water into or out of the cell. Cell size will stay the SAME.

• ISOTONIC

• HYPOTONIC

the movement of molecules LIKE OXYGEN OR HYDROGEN from areas of higher concentration to areas of lower concentration.

• DIFFUSION

• OSMOSIS

molecules LIKE GLUCOSE AND SALT diffuse across the cell membrane with help from membrane PROTEINS, such as channel and carrier proteins.

• FACILITATED DIFFUSION

• OSMOSIS

type of membrane transport that does NOT require energy to move substances across cell membranes. This includes diffusion, osmosis, and facilitated diffusion.

• PASSIVE TRANSPORT

• ACTIVE TRANSPORT

a kind of cellular transport where substances move against a concentration gradient. This type of transport REQUIRES ENERGY from the cell. This includes endocytosis and exocytosis.

• PASSIVE TRANSPORT

• ACTIVE TRANSPORT

process that occurs when a cell moves large materials OUTSIDE of the cell through secretory vesicles. This type of transport is active and requires energy.

• ENDOCYTOSIS

• EXOCYTOSIS

a process by which cells absorb or take in external materials by engulfing it (taking in) with the cell membrane. Examples of this is pinocytosis and phagocytosis.

• ENDOCYTOSIS

• EXOCYTOSIS

a process by which the cell takes in the fluids along with dissolved small molecules. Pre-fix means to drink.

• PINOCYTOSIS

• PHAGOCYTOSIS
