• from low to high concentration
• from  high to low concentration
• from equilibrium to areas of high concentration
• all of the above

Which is true about active transport?

• It requires energy
• it does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

What are two types of passive transport?

• endo and exocytosis 
• cookies and milk
• active and passive 
• Osmosis and diffusion

What does it mean that a cell membrane is semi-permeable?

• It allows all substances in
• It allows some substances in
• It allows nothing in

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall
