Lysosomes are spherical organelles found only in animal cells that contain hydrolytic enzymes. They function as the waste disposal system for the cell by digesting unwanted materials through intracellular digestion. Lysosomes are bound by a single lipid membrane that protects the cell from the digestive enzymes within. They receive their enzymes from the rough endoplasmic reticulum and are produced by the Golgi apparatus. A lack of proper lysosome function can lead to a buildup of waste and cell death.

2. Function Found only in animal cells Filled with enzymes for intercellular digestion Waste Disposal System that is inside of cell Essential to all eukaryotic cells If it is not functioning properly, there would be an accumulation of unwanted materials, which would lead to the death of the cell

3. Relevant Structures Filled with hydrolytic and digestive enzymes Spherical bag-like structure that are bound by a single layer membrane that surrounds it The membrane acts as a protective barrier that protects the rest of the cell from the enzymes that are contained within the lysosome.

5. Alliance Golgi Apparatus, because Lysosomes are manufactured by the Golgi Apparatus Rough Endoplasmic Reticulum, because the enzymes are made by the Rough ER

6. Which Organelle Should Go? Vacuole, because it only stores materials temporarily We believe that the cell could function without it We also believe that they are relatively less important compared with other organelles in the cell
