10. a. List the types of passive transport.

b. Molecules that are too large to move across the plasma membrane must get across through a type of passive transport called __________________ transport.

a. The types of passive transport include:

- Simple diffusion: Movement of substances from an area of higher concentration to an area of lower concentration.
- Facilitated diffusion: Movement of substances with the help of transporter proteins.
- Osmosis: Diffusion of water molecules across a selectively permeable membrane.
