etH - osmosis 11.28.23

During osmosis

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

Where is there a high concentration of water?

• in the flower
• cannot be determined by picture.
• in the vase
• in the leaves

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

• Shrink/Dehydrate
• Expand
