The '''vacuole''' is a large organelle found in [[prokaryotes]] and within the cytoplasm of [[eukaryotic cells]]. It frequently occupies the majority of the space inside [[plant]] cells where it typically exists as single transparent vesicle in mature [[cells]], but small in some meristematic cells. | The '''vacuole''' is a large organelle found in [[prokaryotes]] and within the cytoplasm of [[eukaryotic cells]].

Like most organelles, the vacuole is [[membrane]]-bound compartment, and may function in a variety of systems such as [[digestion]], secretion or excretion. In plants, it plays important roles in the storage of various products, by-products, nutrients and [[water]]. It is also used for sequestering unwanted debris, and toxic materials. In herbaceous [[plants]] it provides turgor pressure necessary for the structural support of soft tissues. Wilting in such plants is due to water loss within the vacuole. | Like most organelles, the vacuole is [[membrane]]-bound compartment, and may function in a variety of systems such as [[digestion]], secretion or excretion.
