Cell Membrane Diffusion Quiz

What is the function of a semipermeable membrane in our cells?

• To produce energy for our cells

• To store genetic information in our cells

• To regulate what goes into and comes out of our cells

What is diffusion?

• The movement of particles into and out of our cells

• The regulation of solute concentration inside and outside the cell

• The movement of particles from areas of high concentration to areas of low concentration.
