Calculate the solute potential of a sucrose solution with a concentration of 0.2M at 25 degrees Celsius. These are exchanged . Personalized gifts for all ages. For example, plant cells often have a large vacuole that takes up a sizable portion of the space within the cell because the vacuole is storing water. Digestive enzymes from the vacuole then degrade the entire cell. Although the vacuole does not take as much dye as other organelles of the cell (the vacuole does not contain many stainable constituents), you can still see and study the structure of vacuoles under a compound microscope. It is a network of membranes called cisternae. Vacuoles are shields for materials that could be harmful to the cell. By having the membranes allows each enzyme to have a specific pH and specific function for making lipids, breaking down sugars, etc. Sometimes, the vacuole can even be used as a compartment to store waste products, so the rest of the cell is protected from contamination. proteins, and other polysaccharides that help maintain the shape. The large vacuole also serves the function of maintaining cell structure, by crowding other organelles into their optimal locations within the cell.
