Cell Biology: Definition of Cell, Types, Structure and Functions
At some point or the other, we’ve all marveled at how diverse the living world around us is. Detailed scientific studies of these organisms only emphasized their diversity even more. However, there also exists unity underlying this diversity — and the theory that emphasizes this unity is the cell theory.
The cell serves as the fundamental structural and functional unit of all living organisms. It is the cell that is a universally common feature in every living organism that ever existed, exists today, and will ever exist in the future. The cellular organization gives rise to a plethora of physiological, biochemical, and behavioral processes that lead to the genesis of life itself.
In order to study these processes in molecular terms, scientists have taken a physio-chemical approach and made use of cell-free systems. They further established this approach by analyzing the elements and compounds present in living tissues. Not only does this met…
