Summary Introduction
Introduction:
Ever organisms present in the environment contains cell. The cell is the basic “fundamental unit” of life. Cell performs a number of important functions. These are termed as cellular activities. Reproduction is also an important cellular activity. All the new cells are formed from the old cell. The process by which a cell produces its progenies is termed as reproduction.
