Diffusion and Osmosis study

What is diffusion?

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

This picture is an example of _________________?

• osmosis
• isotonic
• diffusion
• active transport

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Diffusion and Osmosis are examples of...

• Active Transport
• Passive Transport

Where is there a high concentration of bbq smoke?

• In the bbq pit
• In the house
• Two streets over
• In the atmosphere

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion
