Full Answer
What are your thoughts on cell theory? In biology, cell theory is the historical scientific theory that living organisms are made up of cells, and all cells occur from pre-existing cells. Cells are the fundamental component of structure in all organisms, and they are the basic unit of reproduction. The action of an life form depends on the total activity in independent cells.

Cells are the basic building blocks of all living things because all living things are composed of cells.
The cell theory was given by Schleiden and Schwann, which was later modified by Rudolf Virchow. The three principles of cell theory are: All living organisms are composed of one or more cells. Cell is the basic structural and functional unit of living organisms. All cells arise from pre-existing cells.
In prokaryotes such as bacteria and unicellular eukaryotes like an amoeba, etc. a single cell performs all the functions essential for life. In multicellular organisms, there occurs division of labour and cells are specialised to carry out different functions. A single-cell zygote gives rise to complex multicellular organisms.
A single-cell zygote gives rise to complex multicellular organisms. Cells carry all the genetic information, which is passed on to the offspring at the time of cell division.
All cells arise from pre-existing cells. All the living organisms, be it bacteria or complex multicellular organisms, all are made up of cells. The basic chemical composition of cells remains the same with some differences in the structure of prokaryotic and eukaryotic cells and plants and animal cells. In prokaryotes such as bacteria and ...
