Difference Between Cell Wall and Cell Membrane, Structure

Difference Between Cell Wall and Cell Membrane: It is important to understand the difference between cell wall and the cell membrane because they are commonly confused.

Difference Between Cell Wall and Cell Membrane Overview

• Primary Cell Wall
• The Middle Lamella
• The Secondary Cell Wall

Function of Cell Wall

1. Protecting the cell from physical damage and intrusion by pathogens.
2. Regulating and directing the growth of the cell.
3. Providing structural support and strength and preserving the cell's shape.
4. Serving as a storage repository for carbohydrates, particularly in seeds, to facilitate plant growth.
5. Allowing the unhindered passage of smaller molecules.

Function of Cell Membrane

1. Safeguarding the internal integrity of the cell.
2. Providing support and preserving the cell's structure.
3. Endocytosis and exocytosis are balanced to control cell growth.
4. Facilitating cell signaling and communication.
5. Operating as a selectively permeable barrier, enabling the entry of specifically chosen substances into the cell.

Similarities Between Cell Wall and Cell Membrane

1. The cell wall and cell membrane protect the cell from external mechanical stresses.
2. They play a crucial role in providing shape and rigidity to the cell.
3. Acting as the primary conduits for the entry and exit of molecules, both the cell wall and cell membrane function as essential channels for molecular transport.
4. The cell wall and cell membrane collectively constitute the outermost layer of a cell.
