What are the three main components to cell theory?

1 Answer

Cell theory is one of the basic principles of biology and refers to the idea that cells are the basic unit of structure in every living thing.

Explanation:

The 3 tenets to the cell theory are:-

  1. All living organisms are composed of one or more cells
  2. The cell is the basic unit of structure and organisation in organisms
  3. Cells arise from pre-existing cells

Credit for the cell theory is given to German scientists Theodora Schwann, Matthias Schleiden, and Rudolf Virchow.
The cell theory holds true for all living things, no matter how simple or complex.

The modern version of the cell theory includes the ideas that :-

  1. Energy flow occurs within cells
  2. Heredity information (DNA) is passed on from cell to cell
  3. All cells have the same basic chemical composition.
