INTRODUCTION:-
Vacuoles occur in most , if not all ,cells .They are small in animal cells.

Fungi and plants have large vacuoles.In plants , the vacuoles increase in size as the cell enlarge and a mature cell is almost fully occupied by a central vacuoles that is surrounded by a thin layer of cytoplasm wherein nucleus and other organelles are squeezed .

This is an adaption to quicken the exchange of materials between the cytoplasm and the surrounding environment.

The vacuoles are bubble – like sacs bounded by a single unit membrane called the tonoplast.They are filled with a fluid called cell sap.

The latter consists of free water and a variety of compounds in solution or suspension.
