The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell. It separates the cytoplasm (the contents of the cell) from the external environment. It is a feature of all cells, both prokaryotic and eukaryotic. a 3D diagram of the cell membrane.

The xylem of plants usually contains a number of parenchyma cells, leading some people to classify them as a type of xylem cell, although this is technically incorrect. http://armandoh.org/What is a lipid, how does it form a membrane?What is a fluid mosaic model, and other structures in the inner membrane leaflet?Watch Part The cell membrane is an extremely pliable structure composed primarily of back-to-back phospholipids (a “bilayer”).Cholesterol is also present, which contributes to the fluidity of the membrane, and there are various proteins embedded within the membrane that have a variety of functions. so when you go swimming or showering have you ever wondered why don't your cells in your body fill up with water or why don't the substances in your cells leak into the pool well the reason is because we actually have a very important structure that prevents this from happening this is what we call the cell membrane the cell membrane is what's on the outside of a cells so if we have a very A quiz on cell membranes.

Some cell organelles like ribosomes are not bounded by any membrane. The plasma membrane structure is made up of several components
Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. The cell membrane is a fluid structure that moves and changes. It looks like a mosaic because of the different embedded molecules.
