Why is a vacuole bigger in a plant cell? Since in a plant cell the vacuole is bigger compared to in an animal cell, why is this?

In a plant cell, the vacuole takes up to 90% of the cell. It is filled with cell sap to support th3 cell. The vacuole in a plant cell also maintains hydrostatic pressure to provide structural support. The plant can increase in size by enlarging the vacuole. The main function of a vacuole in a plant cell is to store nutrients and waste products. Most animal cells, excluding fat cells, do not contain vacuoles.
