How could the camera on an iPhone be represented as a large vacuole in a plant cell?

Im doing a cell representation project in school and so I decided to do my iphone as my project. If you don’t get it, the cell wall is the phone case (that usually gets people to understand what i’m talking about) and the mitochondria is the charger… Anyways, I’m doing a plant cell and for the large vacuole(s), the representation is the camera.. I don’t really know why I did that but its a phone so it obviously doesn’t hold water/food/etc. So how could I relate a camera to a large vacuole in the plant cell! And before you ask, its too late to change it. Please help me!
