Passive Transport

This example of passive transport is the movement of water to an area of low to high concentration of solutes. 

• osmosis
• concentration gradient
• isotonic
• facilitated diffusion

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Osmosis is the diffusion of _____ across a membrane

• glucose
• NaCl
• proteins
• water

Passive transport is called "passive" because it occurs WITHOUT

• cause.
• energy.
• a concentration gradient.
• a cell wall.

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

• True
• False
