Diffusion, Osmosis, and Transport

The movement of molecules (matter) from an area of greater concentration (how much of something) to an area of lower concentration. Does not require energy.

• Active Transport

• Passive Transport

• Osmosis

• Diffusion

Double layer of phospholipids. Holds everything in. Decides what can enter or leave the cell.

• Plasma Membrane

• Cell Membrane

• Cell Wall

• Protein Pump

NGSS.MS-LS1-2

A membrane that allows only certain things to pass through

• Cell Membrane

• Cell Wall

• Selectively Permeable

• Border Control

Tags

NGSS.MS-LS1-2

Membrane folds around large substances so they can leave the cell. Requires ATP. Type of active transport

• phospholipid

• solute

• Exocytosis

• Endocytosis

Membrane folds around large substances so they can enter the cell. Requires ATP. Type of active transport

• Endocytosis

• Channel Protein

• Cell Membrane

• Diffusion

NGSS.MS-LS1-2

Channel proteins help polar substances enter/leave the cell. Does NOT require energy, so passive form of transport.

• Active Transport

• Passive Transport

• Osmosis

• Facilitated diffusion

NGSS.MS-LS1-2

The movement of water across a semi-permeable membrane through diffusion. (semi-permeable means lets some things in and not others)

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

Does NOT require energy....the movement of molecules (matter) from an area of high concentration to an area of low concentration. Diffusion is a kind of passive transport.

• Active Transport

• Passive Transport

• Osmosis

• Facilitated Diffusion

A system in which things become equal; all particles (molecules or matter) become equal

• Equilibrium

• Equality

• Balanced

• All Equilibrium

A membrane that allows only certain things to pass through

• Semi-premeable

• Gate membrane

• Border Control

• Cell Membrane
