Osmosis.  Energy requirements?  No energy required  Modes of passive transport?  Diffusion through cell membrane  The movement of a substance from.

How do Materials move in & out of the Cell? They move across the cell membrane by: Passive Transport (no energy required) or Active Transport (energy required)

Cell Transport Cell Transport * Moving substances (such as food, water, waste, and oxygen and CO2) in and out of cells through the cell membrane * There.

Passive Transport transport of molecules across the cell membrane that does not require energy! 3 Types: 3 Types: 1) Diffusion 2) Osmosis 3) Facilitated.

Moving Cellular Material Chapter 2, Lesson 3. Membranes Control the movement of materials in and out of cell. – Semipermeable – only certain substances.

Materials move across membranes because of concentration differences.

Diffusion & Osmosis. Diffusion Diffusion The movement of molecules from an area in which they are highly concentrated to an area in which they are less.

Transporting into Cells - Passive movement from an area of high concentration to an area of low concentration is diffusion. The diffusion of water is called.
