  2. b the bursting of a cell.
  3. c a cell that ingests and destroys (digests) foreign matter or microorganisms.
  4. d the process by which a cell membranes surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.
  5. e the movement of chemical substances, usually across the cell membrane, against a concentration gradient; requires cells to use energy.

5 Multiple choice questions

  1. in protists, an organelle that accumulates water and then releases it periodically to maintain osmotic pressure.
  2. a complex of protein molecules in a cell membrane that form a pore through which ions can pass.
  3. 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.
  4. a carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell.
