Cell Membrane Transport intro

Passive transport is called "passive" because it occurs WITHOUT

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

What is homeostasis?

• How the body releases oxygen
• Passive transportation 
• How the body regulates itself for survival
• Active transport
