What is cell theory?The cell theory is a scientific theory that was initially developed in the middle of the nineteenth century, which states that all living organisms are composed of cells, that cells are the fundamental structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Knowing that all living things are cells helps us comprehend how they are born, grow, and die. That information helps us understand how new life is produced, why creatures take their forms, how cancer spreads, how diseases can be handled, and more. Cells help us grasp life and death: a living creature is alive, while a dead one is dead.
Therefore, flowers, blood, bacteria and skin all are living things made up of cells.
