Unit 2 LT #2: Cell Transport (Passive and Active)

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

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

What type of transport is this?

• Passive Transport

• Osmosis

What type of transport is this?

• Facilitated Diffusion
• Exocytosis
• Active Transport
• Diffusion

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

What is diffusion?

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

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

Someone sprays air freshener.  The scent fills the room.  This is an example of

• active transport
• osmosis
• diffusion
• cellular respiration

In a "high concentration," molecules

• are spread out

• are tightly packed together

• are uncrowded

• are unevenly dispersed

Active transport moves substances against a concentration gradient 

• true
• false 

Active transport allows a cell to move molecules from an area of low concentration to an area of high concentration.

• True
• False
