Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. 2. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. 3. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration Cell membranes are completely permeable to water; therefore, the environment the cell is exposed to can have a dramatic effect on the cell. Isotonic Solutions: contain the same concentration of solute as another solution. When a cell is placed in an isotonic solution, the water diffuses into and out of...
