During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

The term used to describe the diffusion of water.

• Diffusion
• Osmosis
• Selective Permeability
• Equilibrium

The term used to describe when some molecules are able to pass through a membrane and others are not.

• Osmosis
• Diffusion
• Selective Permeability
• Equilibrium

What type of cellular transport uses energy?

Active transport requires energy because...

• The cell is moving something against a concentration gradient
• The cell is moving something with a concentration gradient

Diffusion and Osmosis are examples of...
