Cell Theory And Structure | Biology

The cell theory, one of the most general and basic concept in biology, is formulated from the fundings and ideas of several scientist.

in 1839, the German zoologist, Theodor Schwann, and the botanist matthaas schleiden who were both working on their own stated clearly that the bodies of all animals and plant are composed of cell and the product of cells.

Cells were than commonly described as unit's of live and the building block from which living organisms are made biology, rodolf virchow, stated that all cells come from cells

In the present century, studies connected with virusis and bacteria opened up the field of molecular biology. scientist have now shown that information about the cells make up is in the nuclar acids (deoxyribonucleic acids DNA and ribonucleic acids RNA) of a cell.

Briefly the cell theory and Its States

1. All living organisms are composed of one or more cell.

2. The cell is the structural and functional unit of all living organisms: the basic organizational unit of life

3. All existing cells come from the reproduction of pre existing cells.

4. A cell contains information for its structural and functional development in its nucleic acids. this information is passed down from parent to offspring cells.
