Explanation: 

Detailed explanation-1: -A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

Detailed explanation-2: -However vacuoles are generally said to store water because they generally make up 30% to 80%2 of the plant cell. Thus the cytoplasm, vacuole and all other organelles contain water and contribute to the cells water potential and turgor pressure.

Detailed explanation-3: -Vacuoles store nutrients and water on which a cell can rely for its survival. They also store the waste from the cell and prevents the cell from contamination. Hence, it is an important organelle.
