Passive Cell Transport

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What type of molecules require energy to move in or out of the cell?

Back

Big molecules.

Front

Define Osmosis.

Back

Diffusion of water across a semipermeable membrane.

Front

What is the state called when the amount of water inside and outside of a cell is equal?

Back

Equilibrium.

Front

What are the two types of cell transport?

Back

Passive and Active.

Front

What is Passive Transport?

Back

The movement of materials across the cell membrane without the use of energy.

Front

What is Active Transport?

Back

The movement of materials against a concentration gradient, requiring energy.

Front

What is Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is a Semipermeable Membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is Facilitated Diffusion?

Back

A process where molecules pass through the cell membrane via special proteins without energy.
