Cell Transport

Passive and Active

Passive and Active Transport (3min)

Passive - No Energy

1. Simple Diffusion

2. Facilitated Diffusion

3. Osmosis

Active Transport - Energy (ATP)

1. Protein Pumps

2. Endocytosis

3. Exocytosis

Multiple Choice

How are active transport and passive transport different?

• Passive transport requires energy and active transport does not. 
• Active transport includes diffusion, and passive transport does not. 
• Active transport requires energy, and passive transport does not.
