Key Concepts

Plasma Membrane

The plasma membrane is a lipid bilayer that encloses the cell, serving as a barrier between the cell's interior and its external environment. It plays a critical role in protecting the cell, mediating communication, and regulating the transport of substances into and out of the cell.

Cellular Compartmentalization

Cellular compartmentalization refers to the organization of a cell into different regions that perform specific functions. The plasma membrane is essential for this organization as it delineates the boundary of the cytoplasm, creating distinct internal environments necessary for various cellular processes.

Selective Permeability

Selective permeability is the characteristic of the plasma membrane that allows it to regulate the movement of substances. It permits certain molecules to pass through while restricting others, which is vital for maintaining homeostasis and ensuring that the cell functions correctly.
