Vacuoles are organelles of plant, fungal, and algal cells. They are part of the internal membrane system and are separated from the rest of the cytoplasm by a membrane called the tonoplast. A single large vacuole occupies more than 80 percent of the...

The term vacuole in biology refers to a membrane bound space, filled with liquid, often located in the center of a cell. Vacuoles are especially prominent in plant cells where they may occupy 95% or more of the cell volume. The vacuole was long...

(from French, vacuole: a little vacuum) A vacuole is a small sac or cavity within a CELL. In plants vacuoles are subcellular elements containing a variety of chemicals with important functions relating to growth, development and reproduction. But if...

Space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoans, vacuoles perform functions such as storage, ingestion, digestion, excretion, and expulsion of excess water. The large central...

Vacuoles are found in the cytoplasm of most plant cells and some animal cells. Vacuoles are membrane-bound compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions. Vacuoles and their contents are...
