What is this?
Vacuoles are like stretchy storage bags found inside cells, especially big in plant cells. They hold water, food, waste, and other important materials that the cell needs or wants to get rid of. These sacs help cells stay healthy and, in plants, even help them stand up straight.
Key Parts to Explore
Vacuolar Membrane
This is the flexible outer skin that surrounds the vacuole and keeps everything inside.
Cell Sap
This is the watery liquid that fills up the vacuole, holding many dissolved substances.
Stored Water
A large part of the vacuole's contents is water, which keeps the cell hydrated and plump.
Stored Nutrients
The vacuole safely stores important food molecules and chemicals for the cell to use later.
Did You Know?
Did you know that in some plant cells, one giant vacuole can take up almost 90% of the cell's space, acting like a huge internal water balloon?
