Which biologist proposed the cell theory along with Schwann?


Schleiden and Schwann proposed the cell theory.

A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes. Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life

Cell theory

Cell Theory was proposed by the German scientists,  Theodor Schwann, Matthias Schleiden, and Rudolf Virchow. The cell theory states that:

  1. All living species on Earth are composed of cells.
  2. A cell is the basic unit of life.
  3. All cells arise from pre-existing cells.

A modern version of the cell theory was eventually formulated, and it contains the following postulates:

  1. Energy flows within the cells.
  2. Genetic information is passed on from one cell to the other.
  3. The chemical composition of all the cells is the same.
