Why is the cell membrane refered to as a lipid bilayer?

• It is made of two different types of fats

• It is shaped like a circle

• It is made of lipids and has two layers

The head of a phospholipid is?

What substances move through the cell membrane easily by simple diffusion?

• Polar molecules

• Small nonpolar molecules

• Ions

• Large macromolecules

Substances will continue to move through the cell membrane by simple diffusion until this happens.

• Equilibrium is reached

• The substances are unequal on both sides

• It will not stop it keeps going non-stop
