Lysosomes play an important role in the cell by consuming worn-out structures, attacking bacteria, and containing enzymes to digest materials. A lack of lysosomes can lead to lysosomal storage diseases where waste builds up and disrupts cell function. Lysosomes contain hydrolases and transport proteins and would ally with vacuoles to help digest food particles. They view the cytoskeleton as dispensable since it mainly provides structure and transport within the cell.
