Movement of molecules through the cell membrane from high to low concentration

• passive transport

• active transport

Active transport moves substances against a concentration gradient 

• true
• false 

Which form of active transport is being shown?

• Pinocytosis
• Endocytosis
• Exocytosis
• Osmosis

When cells take in food molecules through active transport, what is it called?

• diffusion

• phagocytosis

• exocytosis

• osmosis

Which is NOT a form of active transport?

• Endocytosis
• Osmosis
• Exocytosis
• Pinocytosis

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

When cells form a vesicle to release materials, which form of transport is occurring? 

• Endocytosis
• Exocytosis
• Facilitated Diffusion
• Osmosis

Human immune cells can engulf bacteria to destroy them. This is an example of 

• pinocytosis
• phagocytosis
• exocytosis
• acidosis
