Yes technology has allowed us not only to study the detailed structure of an organelle but also the molecular function perform by an organelle. e.g by using technology we easily study the molecular function of an organelle as that of mitochondria is energy production we study it by technology like differential centrifugation is used to isolate the organelle and used to study its function. Different type of staining microscopes are used to study the organelle and to isolate them and study their basic function. Gel electrophoresis is a technique use to study DNA.
