Caption: Marine pennate diatoms on stalks (Gomphonema sp.). Stalked, marine pennate diatoms are usually benthic diatoms that produce extracellular stalks. Stalked diatom species produce excessive amounts of extracelluar polymers that are organized in to stalks. These stalks terminated in adhesive pads which attach the stalks to the substrata. From this pad structure the cells propagate stalk material until cells undergo mitosis. Stalks bifurcate at the point of cell division, as each daughter cell continues to produce a stalk.
