Worked practice questions

What does a plant cell gain when osmosis raises turgor pressure?

  1. Support from cell walls
  2. An extra membrane layer
  3. A larger cell nucleus
  4. More chromosome pairs
Show answer and solution

Correct answer: A. Support from cell walls

Water entry raises turgor pressure against the cell wall, supporting plant tissues.

What is the net movement in diffusion generally from?

  1. A membrane to a cell wall
  2. Lower to higher concentration
  3. Higher to lower concentration
  4. One cell to its nucleus
Show answer and solution

Correct answer: C. Higher to lower concentration

Diffusion generally moves particles from higher concentration to lower concentration.

What drives the random movement of particles in diffusion?

  1. A tissue's growth
  2. A fixed water pump
  3. Their random motion
  4. A cell's spindle
Show answer and solution

Correct answer: C. Their random motion

Diffusion is stochastic because the diffusing particles move randomly.
