Which transport does not require energy?

• Passive
• Active 

What is Osmosis?

• equal concentration

• diffusion of water through a selectively-permeable membrane

• movement of sugar through a membrane

• non-polar tail

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

If you put a plant in salt water it will ...

• swell because water diffuses into the cells

• Nothing will happen

• shrivel because water diffuses out of the cell
