- Summary: Definition. The cell membrane , also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell
- Matching search results: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic

- Summary: · JOB: The cell membrane controls what enters and exits the cell and thus protects the cell. Q: So how do things enter and exit the cell?
- Matching search results: Scientists were then able to break apart the cell membrane and find out what chemicals were in it. The current best model of what a cell membrane looks like is in the figure below. As you can see it is made up of two parts. They are the

- Summary: · Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell
- Matching search results: Water and many other substances cannot simply diffuse across a membrane. Hydrophilic molecules, charged ions, and relatively large molecules such as glucose all need help with diffusion. The help comes from special proteins in the membrane known as
