What organelle of the cell produces energy?

• Mitochondria 
• Golgi Body 
• Vesicle

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane.
