5 Matching questions

  1. diffusion
  2. hypotonic
  3. turgor pressure
  4. passive transport
  5. equilibrium
  1. a the movement of substances across a cell membrane without the use of energy by the cell.
  2. b in biology, a state that exists when the concentration of a substance is the same throughout a space.
  3. c the movement of particles from regions of higher density to regions of lower density.
  4. d describes a solution whose solute concentration is lower than the solute concentration inside a cell.
  5. e the pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell.

5 Multiple choice questions

  1. the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated (of the solute) through a membrane that is permeable to the solvent.
  2. a method of active transport across the cell membrane in which the cell takes in extracellular fluids.
  3. the process by which a cell engulfs large particles or whole cells, either as a defense mechanism or as a means to obtain food.
  4. in protists, an organelle that accumulates water and then releases it periodically to maintain osmotic pressure.
  5. the movement of chemical substances, usually across the cell membrane, against a concentration gradient; requires cells to use energy.

5 True/False questions

  1. sodium-potassium pumpa carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell.

          

  2. vesiclea small cavity or sac that contains materials in a eukaryotic cell; forms when part of the cell membrane surrounds the materials to be taken into the cell or transported within the cell.

          

  3. endocytosisthe process by which a cell membranes surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.

          

  4. phagocytethe process by which a cell engulfs large particles or whole cells, either as a defense mechanism or as a means to obtain food.

          

  5. facilitated diffusionthe movement of particles from regions of higher density to regions of lower density.
