By: Colin Lopez, Jon McGrath and Brady Stonesifer Lysosome Lysosomes are vesicles in all cells, which contain digestive enzymes that can break down the wastes contained in the vacuoles. It works as a cleaning system for cells and factories. The Lysosome is located in the cytoplasm of eukaryotic cells. A fun fact about Lysosome The single-layer membrane protects the rest of the cell from the harsh digestive enzymes that would otherwise harm the cell. Vacuole The vacuole is an organelle that is found only in plant cells. It is responsible for maintaining the shape and structure of the cell. Plant cells don’t increase in size by expanding the cytoplasm, rather then increasing the size of their vacuoles. A fun fact about the Vacuoles Vacuoles also help maintain a steady pH. The pH is acidic. Works Cited (n.d.).
