If I could play the role of an organelle, I would want to be a lysosome.
Lysosome derives from the Greek words lysis, meaning "to separate", and soma, meaning "body." They are cells that contain powerful digestive enzymes that digest excess or worn-out organelles, food particles, and engulf bacteria or viruses. They are found only in animals, however, the vacuole of a plant does the same job.
Diseases of the lysosome are Lysosome storage disorders (LSDs). This disorder is inherited and caused by a deficiency of specific enzymes that require the break down glycosaminoglycans. It is a synthetic crystalline compound, lysergic acid diethylamide, that is a potent hallucinogenic drug.
Here is a video link to watch these organelles in the works: https://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter2/animation__lysosomes.html
