Storage vesicles in cells
Vacuoles are cellular organelles that contain mostly water. • Plant cells have a large central vacuole in the center of the cell that is used for osmotic control and nutrient storage. • Contractile vacuoles are found in certain protists, especially those in Phylum Ciliophora. These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to osmotic pre… Web4 Oct 2024 · The main difference between these two is their size. The vacuoles are larger than the vesicles. The membrane of vesicles can diffuse with the membranes of other structures within the cell to accomplish …
