    Start by explaining the function of the two in the two cells, then you'll see the link. They're both extremely important for the cell's function.

    Mitochondria in muscle cells: contraction of muscle fibres by relative sliding of actin and myosin filaments requires energy - provided by mitochondria (explains why muscle cells have numerous, large mitochondria: Jesus, if you believe in the guy, was not silly!!) - salivary gland cell secrete salivary juice (contains salivary amylase [ptyalin]), which, of course, is a protein - hence well-developed ER in these cells (ribosomes = site of protein synthesis) - this process requires energy - provided by mitochondria (also well developed in salivary gland cells) - hence link.
