The term ‘cell’ is initially derived from the Latin word meaning a small room. A cell is the smallest and fundamental unit of all living organisms. The single-cell performs numerous biological activities of a living organism. Therefore, the cell is called the structural and functional unit of all the living species on Earth.
Some organisms like bacteria are made up of a single cell, while other living species are made up of trillions of cells, including animals, birds, plants and human beings. An organism comprises four levels of organization:
Cells
A group of cells form tissues.
Tissues
Tissues make up organs.
Organs
Organs include an organ system.
Organ systems.
