How does a plant cell change with age?

When examining plant cells under a microscope, one can easily distinguish a young cell from an old one by the position of the nucleus. In young cells, the nucleus is located in the center of the cell, while in old cells it is pressed against the membrane. This happens because there are many vacuoles in a young cell, but they are small and do not interfere with the position of the nucleus. And in the old cell, vacuoles merge into one large one, it fills almost the entire volume of the cell and presses the nucleus to the membrane.

With age, the cell ages very actively and at the same time its functions change:

enzymatic synthesis is reduced;
the formation of receptor proteins is also reduced;
the absorption of nutrients is impaired.
