Explain the processes of diffusion and osmosis and their roles within a cell Types of Solutions and their effects on cells  When a cell is in a solution that has the same concentration of water and solutes—ions, sugars, proteins, and other substances—as its cytoplasm, the cell is said to be in an isotonic solution.  Water still moves through the plasma membrane, but water enters and leaves the cell at the same rate. The cell is at equilibrium with the solution, and there is no net movement of water. pg. Questions 33.  8. Explain the processes of diffusion and osmosis and their roles within a cell Types of Solutions and their effects on cells  If a cell is in a solution that has a lower concentration of solute, the cell is said to be in a hypotonic solution.  There is more water outside of the cell than inside. As a result of osmosis, the net movement of water through the plasma membrane is into the cell.  In an animal cell, as water moves into the cell, the pressure increases, and the plasma membrane swells. If the solution is extremely hypotonic, the plasma membrane might be unable to withstand this pressure, and the cell might burst.  Plant cell have a rigid cell wall that supports them, plant cells do not burst when they are placed in a hypotonic solution. As the pressure inside a cell increases, the plant’s central vacuole fills with water, pushing the plasma membrane against the cell wall. Instead of bursting, the plant cell becomes firmer. pg. 34. Questions  8. Explain the processes of diffusion and osmosis and their roles within a cell Types of Solutions and their effects on cells  When a cell is placed in a hypertonic solution, the concentration of the solute outside of the cell is higher than it is inside.  During osmosis, the net movement of water is out of the cell.  Animal cells in a hypertonic solution shrivel because of decreased pressure in the cells.  Plant cells in a hypertonic solution lose water, mainly from the central vacuole. The plasma membrane shrinks away from the cell wall. Loss of water in a plant cell causes wilting. pg. Questions  Q.9 Compare the function of cell organelles.
