It acts as a selective barrier, regulating the entry and exit of substances. It also plays a critical role in communication with the environment and other cells. The plasma membrane is made up of a phospholipid bilayer with embedded proteins, which allows it to be fluid and flexible, adapting to the cell&#8217;s needs.

It is composed of cytosol, a gel-like substance, and contains various organelles in eukaryotic cells or the nucleoid region in prokaryotes. The cytoplasm is where most of the cell&#8217;s metabolic processes occur, including protein synthesis, energy production, and cell division.
