What part of the cell allows the transport of different materials through different modes of cellular transport? Nucleus false Vacuoles false Endoplasmic reticulum false Cell membrane true Single Which of the following is TRUE about simple diffusion? A. It is the simplest type of Active transport false B. It is the simplest type of Passive transport false C. It allows particular ions inside and outside the cell to achieve chemical equilibrium false D. B and C true Single What causes the movement of materials inside and outside of the cell in simple diffusion? Energy in the form of ATP false Existence of a concentration gradient true Carrier proteins false Sodium and Potassium ions false Single Which is TRUE about facilitated diffusion? It needs energy to occur false It is an example of active transport false It needs the “help” of channel and carrier proteins to facilitate the process of diffusion true It diffuses only molecules of water across the semipermeable membrane false Single Which of the following describes a Hypotonic solution? It is a solution that is LESS concentrated with solute molecules true It is a solution that is MORE concentrated with solute molecules false It is a solution that is in equilibrium with another solution false It is a solution with channel and carrier proteins to facilitate movement false Single Cell lysis or breakdown of the cell may occur in what scenario? The cell is in an ISOTONIC solution false The cell is in a HYPOTONIC solution true The cell is in a HYPERTONIC solution false It depends on other conditions false Single The cell’s cytoplasm will shrivel and shrink in what scenario? The cell is in an ISOTONIC solution false The cell is in a HYPERTONIC solution true The cell is in a HYPOTONIC solution false All of the above false Single Which of the following is true about the diffusion of water molecules across the cell membrane? A. It is termed glycolysis false B. It is called osmosis false C. It moves along a concentration gradient false D. B and C true Single What might happen if a red blood cell is placed in seawater? The cell would probably burst false The cell would have no change in size and shape false The cell would shrink and shrivel true None of the above; it depends on other factors as well false Single What would happen to a red blood cell if it is placed in a solution similar to extracellular fluid? The cell would bloat and probably burst false The cell would shrink and shrivel false The cell would have no change in size and shape true None of the above; it depends on other factors as well false Single
