Answer:
THE THREE MAIN COMPONENTS OF ANY PLANT OR ANIMAL CELL ARE:
1. PLASMA MEMBRANE/ CELL MEMBRANE
Structure- a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like.
Function - the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out). It protects the cell and provides stability.
Proteins are found embedded within the plasma membrane, with some extending all the way through in order to transport materials.
Carbohydrates are attached to proteins and lipids on the outer lipid layer.
