Molecules need no added energy to travel through the cell membrane.

• simple diffusion

• passive transport

• complex diffusion

• active transport

Diffusion is a type of this.

• simple diffusion

• passive transport

• complex diffusion

• active transport

In diffusion, molecules travel from a low concentration to a high concentration gradient.

• true

• false

A molecule that travels from an area of high concentration to low concentration is an example of

• simple diffusion

• facilitated diffusion

• transporting proteins

• semi-passive transport

A type of passive transport that involves water passing through a membrane

• hypertonic

• osmosis

• hypotonic

Higher solute concentration

• hypertonic

• hypotonic

• hydrotonic

• tonic

Equal solute concentration

• isotopic
