Osmosis

 In the given scenario what will happen?  An egg with a dissolved shell is placed in pure water for 48 hours.

• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
• The egg will gain water and swell.
• The egg will lose water and shrink.

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
