Key Questions

  • Osmosis is the movement of water through a semipermeable membrane from areas of higher water concentration to areas of lower water concentration.

    This video discusses the changes which occur in plant cells when they are placed into hypertonic and hypotonic solutions.

    A classic experiment which demonstrates osmosis is when eggs (shells removed) are placed into either water or syrup. The movement of water into or out of the egg causes some drastic changes to the eggs.

  • Because osmosis is the diffusion of water.

    Osmosis will move water from areas of higher concentration to areas of lower concentration.

    Here is a video of a lab conducted to test osmosis in eggs placed into different solutions.

    Water flowed out of the egg which was placed into syrup because the inside of the egg has a higher amount of water than syrup has.

    Water flowed into the egg which was placed in distilled water because the distilled water is 100% water and the inside of the egg has a lower amount of water.

    Hope this helps!
