Week 20 Quiz - Diffusion, Osmosis, Active Transport

What would happen if a cell was placed in a solution with high water concentration?

• Water would move out the cell and it would swell

• Water would move out of the cell and it would shrink

• Water would move into the cell and it would swell

• Massive implosion, creating a black hole

What is osmosis?

• Diffusion of water across a cell membrane from a low to high concentration

• Diffusion of water across a cell membrane from a high to low concentration

• Diffusion of water, where the cell membrane engulfs the water molecules to form a vacuole.
