Question

What is the structure, location and function of a cell membrane?

Answer 1

FUNCTION

A cell membrane has 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

STRUCTURE

The cell membrane is a fluid mosaic of lipids, proteins, and carbohydrates.http://telstar.ote.cmu.edu/Hughes/tutori... CLICK HERE FOR DETAILED INFO

LOCATION

A cell membrane can be found around an animal cell. It holds all of the components of the cell together. In a plant cell, it is located on the inside of the cell wall.
