Cell Biology

          

                                                      INTRODUCTION 

A cell is the basic unit of any form of life and the study of the cell and its function is known as cell biology.The discipline  is very old and goes back to the times When Anton van Leeuwenhok was first discovered cell under the microscope . There are some basic organelles common to all cell types  and then some vary unique ones as the cell specialized . Improvement in instrument ,especially in micros cope and staining techniques made it possible to relate cell structure and function from the simple magnifying glass to electron microscope  and imaging techniques. There are many specialized sub fields in cell biology which have become independent subject themselves some of them being cell genetics ,epigenetics , cell cycle and cell metabolism .
