The concentration of a number of ions and other materials is higher in vacuoles than those in cytoplasm - why?

Question

The concentration of a number of ions and other materials is higher in vacuoles than those in cytoplasm - why? (A) Tonoplast has a number of active transport system that pumps ions into vacuole from cytoplasm (B) Through osmosis, a large amount of ions go continuously to vacuole from cytoplasm (C) Cytoplasmic ions enter the vacuole through osmotic flow of water (D) Vacuole is always engaged in the hydrolysis of salts into their ions

Tardigrade Admin · Accepted Answer

In plants, the tonoplast facilitates the active transport of a number of ions and other materials against concentration gradients into the vacuole. Hence, the ions and other materials are present in a concentration which is significantly higher in the vacuole than in the cytoplasm.
