Cells

 

Actually cells are how many

How many cells are there in our body and what is the size of it ?

For an ordinary men the number of cell in his body will be 10,000 crores to 1,00,000 [ 1 lakh ] in our life time.The size of the single cell will be in Microns ( 1 cell = 10 microns ).The micron is also called as in thousand part in a centimeter or In meter it is one by ten lakhs part which is called as a Micron.

While comming under the topic of weight of the it is ren lakhs part of one milli gram of the single cell weighs.

ROBERT HOOK who is one of the biological scientists in the yaer 1665 he had found out the live cell with the help of a compound microscope.

In the year 1839 SKEDN and SHAWAN are one of the two scienticts found out the primary danger will be with the cell which is declared by them.This is only called as the "STUDY OF CELLS" with this we can find out the life time of each cell wil be known and also the behaviour of it.

The cell on the skin will be dead faster and reproduction of it is also more faster.Blood in the body can live days together at the same time the cells in the brain and pulse cells life time will be more that means we can say centuries together.The cells in the heasrt are also having the same long life span.

The observations of Hooke, Leeuwenhoek, Schleiden, Schwann, Virchow, and others led to the development of the cell theory. The cell theory is a widely accepted explanation of the relationship between cells and living things.

The cell theory states:-

 1.All living things or organisms are made of cells and their products.

 2.New cells are created by old cells dividing into two.
 3.Cells are the basic building units of life.
