Passive and 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

Which of the following is not a type of passive transport?

• Diffusion
• Endocytosis
• Facilitated Diffusion

What type of transport is this?

• Diffusion
• Osmosis
• Facilitated Diffusion
• Active Transport

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Osmosis is the movement of _____ across the cell membrane.

• energy

• oxygen

• water

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

The diffusion of water across a membrane is called

• equilibrium.
• osmosis.
• facilitated diffusion.
• active transport.

Which transport does NOT use energy?
