Osmosis & Diffusion Quiz 1

Osmosis is the diffusion of _____ across a selectively permeable membrane.

• food
• air
• water
• oxygen

During diffusion

• solutes (molecules) moves from high to low concentration

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

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.
• Into the cell, so the cell swells.

_______ regulates what enters and leaves a cell.  

• Cell Membrane
