Question

What is the function of the cell membrane?
A)
to protect and support the cell
B)
to increase the number of cells
C)
to control what enters and leaves the cell
Eliminate
D)
to produce macromolecules within the cell

Answer 1

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.yes, cell membrane does maintain the shape of a cell...but this is not its major function! a cell membrane protects the interior contents present in the cell from spilling out into the external environment! it also protects the cell from harmful substances present in the external environment from entering into the cell! amoeba forms different shapes while feeding...you might have noticed this...without a cell membrane it would become clumpsy n like a fluid widout any purpose in its living! cell membrane maintains shape, rigidity an also protects the cell thereby helping it in its survival!! hope ur doubt has got cleared

Answer 2

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
