Draw arrows in the diagrams to show the direction in which water will move. Which of the beakers contains a solution that is hypertonic relative to the bag’s contents? Beaker 2 What will eventually happen to the concentrations in beaker 2? Eventually the concentration of water will reach an equilibrium Name two ways that active transport is different from passive transport. Active requires energy, moves from low to high concentrations, utilizes membrane pumps – Passive does not require energy, moves from high to low concentrations, utilizes membrane – channels What are two example of passive and active transport? Describe each one. Diffusion and osmosis are examples of passive transport, where diffusion is the transport of material from a high concentration to a low concentration and osmosis is the movement of water through a selectively permeable membrane from a high concentration to a low concentration Endocytosis and Exocytosis are example of active transport, where large particles or whole cells move into the cell by endocytosis and large amounts of substances move out of the cell by exocytosis. The direction in which water molecules move during osmosis depends on where the water molecules are more highly concentrated. Study the diagrams below. Decide whether the solution in each beaker is hypotonic, isotonic, or hypertonic in relation to the solution inside the cellulose bag, then write your answer below each beaker. Draw arrows to indicate the direction in which the water will move in each case.
