Compare and contrast between two similar organelles- The cell wall and the cell membrane. I need one of each: one similarity*1 point

Comparison of Cell Wall and Cell Membrane

1. Definition

   • Cell Wall: A rigid outer layer that provides structural support and protection to the cell. It is primarily found in plant cells, fungi, and some prokaryotes.
   • Cell Membrane: A flexible, semi-permeable barrier that surrounds the cell, providing protection and regulating the entry and exit of substances. It is present in all cell types.

2. Structure

   • Cell Wall: Composed mainly of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria, giving it rigidity.
   • Cell Membrane: Comprised of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates, allowing fluidity and flexibility.

3. Function

   • Cell Wall: Provides structural integrity, supports the cell shape, and protects against mechanical stress and osmotic pressure.
   • Cell Membrane: Regulates the transport of materials in and out of the cell and facilitates communication between cells through receptor proteins.

Similarity

1. Protective Role: Both the cell wall and cell membrane serve protective roles for the cell. While the cell wall provides a rigid structure for support in plant cells, the cell membrane acts as a selective barrier that protects the internal environment of the cell from the external one.
