Cell Transport

Most of the cell membrane is made of...

• Lipids
• Carbs
• Proteins
• Nucleic acids

How many layers is the lipid bilayer?

• 1
• 2
• 3
• 4

What a cell needs to transport particles by active transport?

• Sun
• Wind
• Energy
• Channels

The movement of molecules against a concentration gradient

• simple diffusion
• facilitated diffusion
• active transport
• osmosis

The picture is an example of.....movement from low concentration to high concentration. 

• active tranport
• passive transport
• diffusion
• osmosis

During Osmosis

• water moves from high concentration to low concentration
• proteins are built
• water moves when energy is used

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

In a solution of salt water, what is the solute?

• Salt
• Water
• Salt water

This picture shows:

• osmosis
• diffusion
• facilitated diffusion
• active transport
