A vacuole is a way for cells to store
things. Living cells have many things to
store, like food, water, and waste products.
Sometimes these vacuoles will stay inside the cell
permanently, especially when it contains water.
Other times a vacuole might be a temporary place
to hold things until the cell has time to get rid
Cells can make vacuoles easily by taking lipid
molecules and grouping them into a shell. Many of
these lipid molecules already make up the cell
membrane, and other lipid molecules are found
throughout the cell as vesicles (little
vacuoles). The shell that makes up a vacuole has
two layers of lipid molecules, so we call it a
lipid bi-layer membrane. (Just like the
