passive transport

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

What is diffusion?

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