Final answer:
The function of an organism is the outcome of the combined activities and interactions of the constituents of the cell.
Step-by-step explanation:
The function of an organism as a whole is considered the outcome of the combined activities and interactions of the constituents of the cell due to the interdependence of cellular activities. Cells function independently of each other, but they also work together in a coordinated manner to carry out the functions necessary for the survival and functioning of the organism. The cell is the basic structural unit of all organisms and is responsible for overall function.
