Detailed explanation-1: -Cells are called building blocks of life because they are basic structural and functional units of our life. In the different levels of organization in an organism, the cell acts as the basic unit. This means cells form the tissues, organs and organ systems in the different organisms.
Detailed explanation-2: -These observations led two German scientists, named Theodor Schwann and Matthias Jakob Schleiden, to propose that cells are the basic building blocks of all living things.
Detailed explanation-3: -A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
Detailed explanation-4: -The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.
Detailed explanation-5: -The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.
