Diffusion and Osmosis

All cells have a cell __________________ which allows some substances to enter

• wall

• membrane

• mitochondria

• vacuole

The cell membrane allows ALL substances to enter and exit the cell.

• TRUE

• FALSE

We can say that the cell membrane is __________________, meaning that it only allows some substances to enter and exit the cell.

• semi-active

• active permeation

• permeable

• semi-permeable

Which is NOT a way that substances enter and exit the cell?

• active transport

• diffusion

• cell gate

• osmosis

What are 2 substances that can pass through a cell membrane?

• oxygen and carbon dioxide

• fats and starch

• chlorophyll and water

• none of the above

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

Diffusion and Osmosis are examples of...

• Active Transport
• Passive Transport

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient

Permeable means

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

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport
