Do you agree that "$A$ cell is a building unit of an organism"? If yes, explain why.

(N/A) Yes, $I$ agree that a cell is the building unit of an organism.
$1$. Structural Basis: Just as bricks are the building blocks of a building, cells are the fundamental structural units of all living organisms.
$2$. Functional Basis: All life processes, such as metabolism, respiration, and reproduction, occur at the cellular level.
$3$. Organization: Cells organize to form tissues, which form organs, organ systems, and finally the complete organism. Therefore, the cell is the basic unit of life.
