The CELL THEORY, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology.

1)Cell is the unit of structure, physiology, and organization in living things.

2) The cell retains a dual existence as a distinct entity and a building block in the construction of organisms.

3) Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).

Sir I think that B option is also included in cell theory.

Because said that there was no life without cell.

Life was started from cell.
