Why are vacuoles small in a young cell?

Vacuoles are membrane organelles that are characteristic of plant cells. They store a supply of cellular juice inside themselves. It consists of water and some organic substances dissolved in it. An old plant cell is very easy to distinguish from a young vacuole. The old cell has a very large vacuole. It can take up most of the cell space. Everything is connected with the vital processes of the cell. Water does not enter the old cell so quickly, the thickness of the cell wall also increases, and so on. Therefore, it is necessary to increase the reserves of cell juice.
