Unicellular organisms, cells perform all the basic actions and functions required for living like nutrition, respiration, reproduction etc.
In multicellular organisms, cells divide their tasks on the basis of "DIVISION OF LABOUR" to specialize in certain functions besides respiration etc. Like conduction in neurons, excitation in muscles, RBC production by bone marrow etc.
The rate of doing work is called power of an object.
It is also defined as the work done by an object per unit time. Mathematically, its formula is given by :
, W is work done and t is time taken.
The SI unit of power is watts and its commercial unit is kWh.
1 watt = J/s or N-m/s.
