If you were making a model of a lysosome, what are parts you would have to label?

The lysosome is a small body or vesicle, which contains enzymes used in digestion, found within the cytoplasm of a eukaryotic cell. These enzymes are reactive enough to break down cellular components, so they are stored within the cytoplasm with a protective membrane that composes a vesicle. So a lysosome is composed of enzymes and a membrane to surround them.

Lysosomes act in three different ways: phagocytosis, endocytosis, and autophagy.  Phagocytosis is the process by which a foreign body is engulfed by the cell wall, forming a vacuole. Vesicles can attach to the vaculoe, forming a lysosome, and break the foregin body down. Endocytosis is a process where the cell wall components themselves can be broken down and recycled by a lysosome. Autophagy is the process in which different internal cellular components are contained and degraded, such as worn-out mitochondria.  See the links for more info:
