Active and Passive Transport

Where is there a low concentration of dye?

• at the bottom of cup

• in the color

• at the top of cup

• no concentration gradient

The picture below is an example of _________________.

• osmosis

• active transport

• diffusion

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Semi-permeable means...

• certain things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

Passive transport requires no...

• concentration gradients

• osmosis

• motion

• energy

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere
