Protons have a positive charge, while neutrons have no charge. Together, protons and neutrons form the nucleus and are responsible for the stability of the atom. Surrounding the nucleus are electrons, which have a negative charge and orbit the nucleus in various energy levels or electron shells. The nucleus is highly dense and compact compared to the electron cloud surrounding it.

What is cell membrane?The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.
When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that substance are moving their own concentration gradients.
Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
