What is Cell?

Cell is the smallest structural and functional unit of living organism.

The cell theory was Proposed by Matthais Schleiden and Theodor Schwann in 1839.
All living organisms are made up of one or more cells.
The cell is the basic unit of life.
All cells come from the division of pre-existing cells.
Cells are of many shapes and sizes, although most are microscopic.
Most cells are small, about 0.001 cm in length (10 μm).
The smallest cells of the microorganism mycoplasma are 0.3 μm in size.
Some cells are large. e.g. some giant algal cells may be several centimeters long.
A chicken’s egg is a single cell. We produce about 2.5 million new red blood cells every second.
Each square cm of your skin contains about 1,50,000 skin cells. Human beings are composed of about 50 to 100 trillion cells.
