1. What is the difference between a solvent and a solute? A. A solvent is formed by organic molecules, where a solvent is formed by inorganic molecules. B. A solvent is the dissolved substance of organic and inorganic molecules, where the solute is the dissolving agent of water. C. A solvent is the cytoplasm and extracellular environment of the cell, where the solute is the external environment that facilitates communication. D. A solvent is the dissolving agent, composed of water and numerous of organic and inorganic molecules, where the solute is the dissolved substances. E. The solvent maintains the steady state of the cell, where the solute regulates the movement of materials across the cytoplasm. 2. Water and selected solutes move passively through the cell and the cell membrane by a physical process called diffusion. What is diffusion? A. The movement of molecules through a semi-permeable membrane from an area of lower concentration to an area of higher concentration B. The movement of molecules through a semi-permeable membrane from an area of higher concentration to an area of lower concentration. C. The movement of molecules across a semi-permeable membrane until there are equal amounts on each side of the membrane. D. Molecules desire to spread as far from the membrane as possible. E. Selected solutes regulate the movement of molecules across a semi-permeable membrane until there is an equal amount of charge on each side of the membrane. 3. Which of the following is true of diffusion? A. Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other. B. Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution. C. Diffusion of particles against the concentration gradient will occur until random motion occurs. D. Diffusion of particles against the concentration gradient will occur until all the particles have dissolved. E. Diffusion of particles either along or against the concentration gradient will occur until all particles have dissolved and remain equally distributed in all areas of the solution. 4. According to the text, Diffusion and Osmosis, selectively permeable means? A. Organelle membranes and the plasma membrane allow water to permanently pass through without regulating the movement of the solutes. B. Organelle membranes and the plasma membrane allow water to freely move stuck solutes through an insoluble membrane. C. Organelle membranes and the plasma membrane allow water to freely move through while regulating the movement of solutes. D. Organelle membranes and the plasma membrane allow water to freely move through while increasing the concentration of solutes. E. Organelle membranes and the plasma membrane allow water to freely move through while decreasing the concentration of solutes. 5. Osmosis is a type of diffusion, what happens in the cell during osmosis? A. Osmosis is the diffusion of water through a selectively permeable membrane from a region where it is highly concentrated to a region where its concentration is lower. B. Osmosis is the diffusion of water through a selectively permeable membrane that requires energy to move across. C. Osmosis is the diffusion of water through a selectively permeable membrane that large or oddly shaped concentrations can move across. D. Osmosis is the diffusion of water through a selectively permeable membrane that requires the synthesis of proteins to move across. E.
