Cell organelles can be defined as specialized subunits of a cell that perform specific functions. These organelles are enclosed by a membrane and form various separate intracellular compartments. Likewise organs are specialized body structures that with specific functions.
Thus, membrane-bound organelles present in an eukaryotic cell and organs of a multicellular organisms function similarly as they both perform vital and specific functions, required for life.
membrane bound organelles in a cell actually contain DNA of their own so they don't have to actually rely on the rest of what the cell is doing in a similar manner, just because your breathing doesn't mean that your kidneys are working at the same time each one is actually independent of its own actions
