Here's why:

* Vacuoles are large, fluid-filled sacs found in both plant and animal cells. However, they are significantly larger in plant cells.

* Plant vacuoles play a crucial role in storing water, nutrients, and waste products. They also contribute to cell turgor (rigidity), which is essential for maintaining the plant's structure.

* Animal vacuoles are generally smaller and more numerous, and their primary function is to store and transport materials within the cell.
