• Concentration gradient

• Diffusion

• Active Transport

Why would a plant cell become wilted in a concentrated sugar solution?

• the cell would gain water by the process of osmosis

• the cell would lose water by the process of osmosis

• the cell would lose water because of active transport

• the cell would gain water because of active transport

What is being demonstrated here?

• Simple diffusion

• concentration gradient

• passive

• active

• equilibrium
