A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.
The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions. One is to introduce nutrients into the cell while removing toxic chemicals from it. Another is that the cell's plasma membrane, which is its outer membrane, will have proteins that interact with other cells. These proteins may be glycoproteins, which also contain a sugar moiety, or lipid proteins, which contain both a protein and a fatty acid. Proteins that stick outside of the plasma membrane also allow for cell-to-cell communication. The cell membrane also provides some structural support.

Explanation:
Natural killer cells are cytotoxic cells that help our body in innate immune response. These are an critical and important component of the innate immune system of our body. These natural killer cells provide a rapid response towards the virus infected cells. These cells have capability to detect MHC that are present on the infected cells. Natural killer cells do not require activation for killing those cells which are missing MHC I. Due to this feature, they are named as the Natural killer cells. These cells can directly induce the death of tumor cells and play an important role in immunosurveillance.
