MYP5 - Osmosis and diffusion

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

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

Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
• the diffusion of particles from an area of high concentration to an area of low concentration
• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
• the diffusion of particles from an area of low concentration to an area of high 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.
