What do central vacuoles do?
, the composition of which can vary (even between vacuoles in the same cell), but is principally water. Water tends to move along concentration gradients into vacuoles. Vacuoles perform different roles in different organisms and these functions include the capture of food, the maintenance of internal hydrostatic pressure (store water), the containment of waste products, the maintenance of an acidic internal pH, the storage of small molecules and finally can enable a cell to elongate rapidly.
