Unit 2 Cell Transport

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

Movement of materials from high to low concentration through a protein channel. 

• Passive Transport
• Active Transport

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport
• Active Transport
