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
