Another plausible explanation for the link between high soda intake and low bone mass is that soft drinks often elbow out calcium-rich milk as individualsâ drink of choice.
To clarify, all cells have a plasma membrane. The function of the cell membrane is to protect the cell and control the transport from the inside to the outside of the cell. It contains transport signaling systems such as protein channels through which substances such as salts pass.
Functions of the Cell Membrane. Both eukaryotic cells, including plant cells and animal cells, and prokaryotic cells, e.g. bacteria, are enclosed by a cell membrane. A cell membrane (see the simple diagram on the right) is a thin structure that is also known as the plasma membrane. The main functions of the cell membrane are: to maintain the physical integrity of the cell - that is to mechanically enclose the contents of the cell, and also.
