All organisms are composed of one or more cells
Cells are the smallest living units of all living organisms
Cells arise only by division of previously existing cell
This cell theory is proposed by German scientists named Matthias Schleiden and Theodor Schwann
Plasma Membrane
Encloses the cell and controls what goes in and out
Plasma membrane has a double layer of phospholipid molecules.
A phospholipid molecule is made up of glycerol which is a phosphate group and two chains of fatty acid.
Fats
Protein molecules are also found embedded in phospholipids.
The membrane is composed of both protein and phospholipid molecules.
Function:
Serves as the boundary between the outside environment and the inside of the cell.
Gives form and shape to the cells.
Connects one cell to two or more adjacent cells.
Cell membrane is also responsible for…
