Plasma Membrane

Plasma Membrane
By: Kia Gallmon

A microscopic membrane of lipids and proteins that forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in and out of the cytoplasm. All cells are surrounded by a plasma membrane. The membrane is composed of a phospholipid bilayer arranged back-to-back. The membrane is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell.

Summary: 

The membrane is made up primarily of lipids and proteins and a 

very small percentage of it is made of carbohydrates. 

The lipids make up the lipid bilayer, which is the primary 

structure of the cell membrane. The plasma membrane is 

a prominent part of the cell that is a critical for a cell's survival. I 

personally  liked learning about the plasma membrane
