A vacuole (/ËvaekjuËoÊl/) ËvÃ¦kjuËoÊl is a-membrane bound organelle which is present in all plant and fungal cells and some, protist animal and bacterial. cellshe function and significance of vacuoles varies greatly according to the type of cell in which they are present, having much greater prominence in the cells of plants, fungi and certain protists than those of animals and bacteria. In general, the functions of the vacuole include:
A vacuole is a cell organelle; is it basically a membranous bag filled with fluids. Vacuoles store water and certain materials that are water-soluble. They are present in all plant and fungi cells.They are also found in some species of bacteria and in some animal cells.In plants and fungi, vacuoles store water and some pigments, and they also provide turgor pressure to support the cells from within.acuoles store water and certain materials that are water-soluble.
