PLASMA MEMBEANE
It is also known as cell membrane.
It seperates the interion one from the outside one.
It is present in the animals
CELL WALL
It is present in the plants only.
It protects the plants.
It gives the plant support to upright.
hope it helps you
BASIS FOR COMPARISON PLASMA MEMBRANE CELL WALL
Meaning Plasma Membrane is a delicate, thin structure of around 5-10nm wide and is visible under electron microscope, and it is present in all types of cell, helps in the passage of molecules and protects the protoplasm. Cell Wall is a thick, rigid structure of around 4-20um wide and is visible under light microscope; it is present in plant cell, bacterial and fungal cell, helps in providing
shape and rigidity to the cell.
Presence Plasma Membrane is present in all types of cells. Cell Wall is present in the plant cell, bacteria, fungi and algae.
Composition Made up of lipids and proteins and carbohydrates. Made up of cellulose (plant cell), chitin (fungi), and peptidoglycan (bacteria).
Structure Thin layers and is visible only through the electron microscope. Thick layers which are visible through the light microscope.
Permeability Semi-permeable. Completely permeable.
Receptors Plasma membrane have receptors, helps in cell-cell communication. Cell wall does not have receptors.
Metabolic function Metabolically active and living. Inactive and non-living.
Thickness Same thickness throughout its life. Thickness grows with life.
Nutrition Need proper nutrition to survive. Doesn't need any nutrition from cell but deposition instead.
Functions 1.Protects protoplasm.
2.It separates the components present inside to outside environment.
3.Helps in cell-cell communication.
4.It allows the passage of molecules 1.Cell wall provides rigidity to the cell, protect the cell from external shock and other mechanical forces.
2.It is responsible for cell morphology.
3.It prevents large molecule to enter into the cell.
4.Also, prevent the cell from being toxic.
5.Helps in maintaining the osmotic environment of the cell.
