Which type of passive transport uses proteins to help molecules pass through the membrane?
Cell membranes are described as selectively permeable.
Four students were asked to explain what this means. Which one is correct?
Student 1: Cell membranes prevent all materials from entering the cell.
Student 2: Cell membranes only provide structural support for the cell.
Student 3: Cell membranes regulate which substances can enter and exit the cell.

Which part of the cell controls the movement of substances?
mitochondria
cell membrane
chloroplast
nucleus
