Osmosis

• Osmosis is the movement of water molecules from a higher to lower concentration through a semi permeable membrane.
• Osmosis is passive. This means it requires no energy.
• A dilute solution is a solution with a high amount of water molecules.
• A concentrated solution is a solution with a high amount of solute and a low amount of water molecules.
• A hypertonic solution is a solution with a higher solute amount than water molecules.
• A hypotonic solution has a higher amount of water molecules than solute.
• An isotonic solution has the same amount of solute than water molecules.
• Plants absorb water in the roots through osmosis.
