Detailed explanation-1: -A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.

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 the basic structural and functional unit of life as they are the smallest unit that can be called living. One complete cell is capable of performing all the physiological activities. Cells combine to form tissues, which are a collection of cells performing a similar function.

Detailed explanation-4: -The cell theory states that cells form the building blocks of life. It introduces the properties of cell. It was proposed by Matthias Schleiden and Theodor Schwann.

Detailed explanation-5: -Cell theory states that all living organisms are made of the cell which is either unicellular or multicellular. Cell serves as the functional unit of life as it involves in the formation of new cell and other cellular components that are essential for life processes.
