Passive vs Active Transport

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentraiton

• high, low
• low, high
• water, salt
• active, passive

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
• isotonic
• diffusion
• active transport

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Permeable means

• 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
