Functions of Plasma Membrane
The plasma membrane acts as a physical barrier between the cytoplasm and extracellular space and allows biochemical reactions necessary for life to occur. The functions of plasma membrane are as follows:
- Barrier: Separates cell contents from the external environment.
- Selective Permeability: Regulates the entry and exit of substances.
- Cell Communication: Contains receptor proteins for signal detection.
- Cell Cohesion: Adhesion proteins help cells stick together.
- Endocytosis & Exocytosis: Facilitates material transport in and out of the cell.
- Homeostasis: Maintains internal balance by controlling molecule movement.
- Environment Interaction: Governs interactions with surrounding cells and molecules.
- Recognition: Displays unique patterns for cell identification.
- Flexibility: Allows cells to change shape and respond to the environment.
- Supports Essential Functions: Essential for cell survival, growth, and reproduction
Plasma Membrane – Definition, Structure, Components, Functions
The plasma membrane acts as a protective barrier made of a lipid bilayer with embedded proteins that separates the interior of the cell from its external environment. The plasma membrane, also known as the cell membrane, is a vital component of the living organism that regulates the movement of substances into and out of the cell. It also participates in cell signaling and adhesion and contributes to the overall functionality and integrity of the cell which maintains a stable internal environment.
