Which of the following is correct about vacoule?
1 In many cells, as in protists, food vacuoles are formed by engulfing the food particles.
2 In plant cell the vacuole can occupy up to 90 per cent of the volume of the cell.
3 The vacuole is the membrane-bound space found in the cytoplasm.
4 All of these
Explanation:
The vacuole is the membrane-bound space found in the cytoplasm. It contains water, sap, excretory product and other materials not useful for the cell. The vacuole is bound by a single membrane called tonoplast. In plant cells the vacuoles can occupy up to 90 per cent of the volume of the cell.

Why the concentration of a number of ions and other materials is higher in vacuoles than those in cytoplasm?
1 Tonoplast has a number of active transport system that pumps ions into vacuole from cytoplasm
2 Diffusion allows a large amount of ions to move into vacuole from cytoplasm
3 Cytoplasmic ions enter the vacuole through osmotic flow of water
4 Vacuole is unable to store , so ions move themselves along concentration gradient
Explanation:
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.
