The movement of substances through the cell membrane without the use
of cellular energy
Used to help substances enter or exit the cell membrane
When energy is required to move materials through a cell membrane
When the molecules of one substance are spread evenly throughout
another substance to become balanced
A vacuole membrane fuses (becomes a part of) the cell membrane and the
contents are released
