5 Matching questions

  1. vesicle
  2. phagocyte
  3. exocytosis
  4. carrier protein
  5. osmosis
  1. a a cell that ingests and destroys (digests) foreign matter or microorganisms.
  2. b the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out.
  3. c 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.
  4. d a protein that transports substances across a cell membrane.
  5. e a 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.

5 Multiple choice questions

  1. the process by which a cell engulfs large particles or whole cells, either as a defense mechanism or as a means to obtain food.
  2. the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins.
  3. a carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell.
  4. describes a solution whose solute concentration is higher than the solute concentration inside a cell.
  5. the process by which a cell membranes surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.
