The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds thecytoplasmof acell. 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 attachmen...
The cell membrane maintains the physical integrity of the cell. It's most obvious in the cases of animal cells (because they don't have cell walls) that the cell membrane holds the cell together by enclosing the cytoplasm and organelles within it. The cell membrane forms a barrier between t...
What does the cell membrane do in a plant? Discover the cell membrane function in plant cells. Learn about its composition, how it works, and its...
The cell membrane has several functions that are integral to the health of the cell. The functions of the cell membrane include physical and barrier functions as well as regulatory functions. Cell Membrane Functions One function of the cell membrane is to provide the cell with shape and structure...
A cell membrane is the thin, fragile and outermost barrier that separates the internal contents of a cell from the external.
The cell membrane – also called the plasma membrane or cytoplasmic membrane – is among the most fascinating and elegant constructs in the world of biology. The cell is considered the fundamental unit or "building block" of all living things on Earth; your own body has trillions of them, an...

Cell membrane, thin membrane that surrounds every living cell. The cell membrane functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from th
A cell, in biology, is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized fun
In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow ...
