What happens on the outer surface of a cell?

The outer surface of a cell is surrounded by the plasma membrane, which marks the boundary between the cellular content and the external medium. The plasma membrane is a continuous film made up of molecules of lipids, proteins, and carbohydrates. Lipids form a double layer and proteins are arranged in an irregular and asymmetric way between them. These components have mobility, which gives the membrane a high degree of fluidity. It acts as a semipermeable and selective barrier regulating the chemical composition of the cell.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
