Eukaryotic cells are cells that contain a nucleus and organelles. Organelles are membrane-bound structures within eukaryotic cells that serve a specific function within the cell. The shape of an organelles is often complementary to the organelle's function within the cell. All organelles work together for the overall survival of the cell, much like all organ systems work together for the overall survival of an organism.
Lysosomes are vesicles that are pinched off by the Golgi apparatus. Within a eukaryotic cell, lysosomes serve in the digestion and removal of wastes. Digestive enzymes are housed within lysosomes. These enzymes are created by the endoplasmic reticulum. Lysosomes engulf other organelles that are no longer functioning, debris, viruses, bacteria, and/or toxins within the cell. The digestive enzymes within the lysosomes then break down this engulfed material.
