The Cell Membrane is Semi-Permeable or Selectively Permeable.

This means it only allows certain substances to enter/exit the cell.

It is also called the “Phospholipid Bilayer”

SEMI-PERMEABLE

Page 3: (Phospholipid Bilayer). The Cell Membrane is Semi-Permeable or Selectively Permeable. This means it only allows certain substances to enter/exit the cell.

Phospho= Phosphate

Lipid= Fat

The cell membrane is made of phosphate and fats.

Bilayer = two layers.

So, two layers of phosphate and fat

WHAT “PHOSPHOLIPID” MEANS

Page 4: (Phospholipid Bilayer). The Cell Membrane is Semi-Permeable or Selectively Permeable. This means it only allows certain substances to enter/exit the cell.

The Cell (Plasma) Membrane is made of many phospholipids joined in a chain.

A single phospholipid looks a sperm with two heads.

The phosphate head attracts water

The fatty (lipid) tail repels water

MANY PHOSPHOLIPIDS

The water-loving head is HydroPHILIC

“PHILOS” is Latin for Love

The Fatty Acid tail is HydroPHOBIC

It’s afraid of water
