Here's a breakdown of its role:
* Water storage: Vacuoles are large, fluid-filled sacs that can occupy a significant portion of a plant cell's volume. They act as reservoirs for water, maintaining turgor pressure, which helps plants stand upright.
* Biomolecule storage: Vacuoles can store various biomolecules, including:
* Sugars: For energy reserves and transport.
* Proteins: For structural support and enzymatic activity.
* Pigments: For color and protection from UV radiation.
* Waste products: To isolate harmful substances from the cell.
While vacuoles are prominent in plant cells, they are also present in animal cells, although generally smaller and with less significant storage functions.
