Which cell organelle is full of watery sap what two functions does it carry out?

The cell organelle that is full of watery sap is the vacuole. It primarily serves two functions: first, it helps maintain turgor pressure within the cell, supporting its structure and rigidity; second, it stores nutrients, waste products, and other substances, contributing to the cell's overall homeostasis. In plant cells, vacuoles can also play a role in the degradation of complex molecules.
