Which of the following option is not the function of the vacuole?

The vacuole is a membrane-bound organelle found in plant and fungal cells. It has various functions such as maintaining the turgor of plant cells, providing the aqueous environment for the accumulation, and also playing a role in the growth of the cells.

However, preparing food through photosynthesis is not a function of the vacuole. Photosynthesis occurs in the chloroplasts, another organelle found in plant cells.
