Study Notes
Osmosis Basics
- Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane.
Direction of Water Movement
- In osmosis, water moves from an area of high water concentration (hypotonic solution) to an area of low water concentration (hypertonic solution).
Purpose of Osmosis in Cells
- The purpose of osmosis in cells is to maintain cellular balance and regulate the concentration of solutes within the cell.
Concentration of Solutes
- A solution that has a higher concentration of solutes than the cell is called a hypertonic solution.
- A solution that has a lower concentration of solutes than the cell is called a hypotonic solution.
- A solution that has the same concentration of solutes as the cell is called an isotonic solution.
Effects of Hypotonic Solution on Cells
- When a cell is placed in a hypotonic solution, water rushes into the cell, causing it to swell and potentially burst (lyse).
