Why concentration of number of ions and other materials is higher in vacuole than cytoplasm?

1. Vacuolar membrane is permeable for all substances
2. Tonoplast facilitates transport against concentration gradient
3. Vacuole is non-membrane structure
4. Vacuoles store and synthesize ATP to absorb ions and materials
