Detailed explanation-1: -The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells.
Detailed explanation-2: -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.
Detailed explanation-3: -Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane-which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments.
Detailed explanation-4: -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.
