Question: What is the function of the cell membrane?
op

Answer: Many, many specific functions, but they can best be summarized this way:
the cell membrane forms a barrier between the inside of the cell and the outside,
so that the chemical environments on the two sides can be different. The cell controls
those differences so as to optimize the workings of the chemical machinery inside the
cytoplasm. The cell also causes brief changes in the internal environment by moving
stuff across the membrane in a controlled way. These changes are the ways in which
cell respond to events in the outside world. -ProfBill

Answer 3

the function of a cell membrain is to assist enzymes of course, and further more, within the membrain are many other vital cells, not cell phones or terrorist cell packets, but the cell membrain is usually one of the billions of cells that takes flight and skyrockets into the nebula of gray matter in the vicinity where all physical and emotional processes are developed.

Answer 4

"The cell membrane (also called the plasma membrane or plasmalemma) is a semipermeable lipid bilayer common to all living cells. It contains a variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes. It also serves as the attachment point for both the intracellular cytoskeleton and, if present, the cell wall." From Wikipedia

Answer 5

Controlling what goes in and out of the cell.
Anchoring of the cytoskeleton to provide shape to the cell
Attaching to the extracellular matrix to help group cells together in the formation of tissues
Transportation of particles by way of ion pumps, ion channels, and carrier proteins
Containing receptors that allow chemical messages to pass between cells and systems
Participation in enzyme activity important in such things as metabolism and immunity

Answer 6

Oh and if you wanna pass, you better learn how to spell membrane correctly!!
Just do a google search if you really want to cheat

Answer 7

No. Write it yourself, you lazy git.
