phospholipid?

A.) the molecules that make up the cell membrane

B.) the molecules that provide structure to plant cells

C.) the smaller pieces that make up proteins

A.) the molecules that make up the cell membrane

Explanation:

Phospholipids are the molecules that makes up the cell membrane. They are lipid layers which gives support and regulates the movement of materials in and out of the cell.

The phospholipid is very important for the building of membrane round a cell. They are made up of rich lipid layer which is made up of phosphoric acids, nitrogen base, alcohol and fatty acids.

With these molecules, they are able to stabilize and regulate the movement of materials in and outside of the cell.
