Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
Phospholipids are the most basic component of the cell membrane. They form a bilayer structure, with hydrophobic tails facing inward and hydrophilic heads facing outward, creating a semi-permeable barrier around the cell.

Most of the functions of a cell membrane are performed by proteins, which act as channels, carriers, receptors, and enzymes. These proteins help regulate the transport of molecules in and out of the cell, facilitate cell signaling, and maintain the cell's structural integrity. Lipids also play a crucial role in maintaining the fluidity and barrier function of the cell membrane.

The human cell has three principal parts which are the plasma membrane, cytoplasm, and the nucleus. The outer boundary is the plasma membrane.
The phospholipid bilayer is the main structural component of membranes, providing a barrier that separates the internal environment of cells from the external environment. Proteins embedded in the membrane play a key role in various active functions, such as transport of molecules, cell signaling, and cell recognition. Cholesterol also contributes to membrane fluidity and stability, affecting membrane function.
Many functions of the plasma membrane are carried out by proteins embedded within the lipid bilayer. These proteins include transporters for moving molecules in and out of the cell, receptors for cell signaling, and enzymes that catalyze chemical reactions. The lipid bilayer itself provides a barrier that separates the cell's interior from the external environment.

Cells have methods other than diffusion/osmosis to move materials across the cell membrane, most of which involve membrane proteins and require the use of energy. The cell membrane also performs functions other than controlling the movement of materials into and out of the cell, and the membranes of some specialized cells have very complex functions. So we can see that the cell membrane is a very intricate and important component of the cell.

One of the most important functions of the cell membrane is to regulate the movement of dissolved substances (such as ions and nutrients) across the membrane. This selective permeability helps maintain internal cellular conditions and control the exchange of molecules with the external environment.

The component that moves the furthest in paper chromatography is the one that is most attracted to the solvent and has the least interaction with the paper. This usually means that the component is less polar than others and is better able to dissolve in and be carried by the mobile phase.
