Expert Answer:

Where cell is the basic functional unit of life, there exists a life among every individual.The cells may be single-celled or made up by many trillion of cells that are grouped into specialised tissues and organs.A group of cells forms a tissue, and a group of tissues forms an organ (heart) and groups of organs form and organ system, (nervous system) and a group of organ systems form an organism(human).
