Functions of the Cell Membrane: The cell is enclosed by a single membrane called cell membrane. Cell membrane separates internal cells environment from its surroundings. The cell membrane is also known as Plasma membrane or plasmalemma. The cell membrane is a thin wall comprises of the unyielding framework of polysaccharide chains that are crosslinked with the help of short peptide chains. The cell membrane outer surface is coated with lipopolysaccharide.
Functions of the Cell Membrane
Functions of the cell membrane are very diverse due to its complex structure. the cell membrane, the principal lipids are phospholipids, sphingolipids, and cholesterol. An imperative feature of these lipids is they are the collection of hydrophobic (water-insoluble) hydrocarbon sections and hydrophilic (water soluble) units. Cell membrane comprises charged units (e.g. Phosphate or amino groups) and uncharged units (e.g. Hexose). In water, such compounds positioned themselves in such a technique that only the hydrophilic section is exposed to water.

Main Functions of the Cell Membrane:
The cell membrane performs many important functions:
- Cell membrane clasps the cell in the organized form.
- The cell membrane is a selectively penetrable or permeable membrane which permits water, certain compulsory nutrients, and metal ions to permit freely among it.
- Cell membrane stashes waste products
- Cell membrane keeps out toxic materials from the cell.
- Cell membrane comprises receptors to bind monitoring substances
- Cell membrane binds to hormones which regulate the countless metabolic activities.
- Cell membrane assists as a sordid of attachment for the cytoskeleton in some organisms.
- Cell supports the cell and supports in maintaining the shape of the cell.
- The cell membrane is the collection of lipids and proteins.
- In cell membrane Lipids provide flexibility to cell membranes and proteins preserve the chemical microclimate of the cell and also aid in the transmission of molecules across the membrane.
