Question

In the temporary mount of onion peel the vacuole is present at which position?

Answer 1

The function and significance of vacuoles vary widely depending on the type of cell in which they are found, with plants, fungi, and certain protists having far more prominent vacuoles than mammals and bacteria.

Complete answer:
To Make a Stained Onion Peel Temporary Mount
Fill a watch glass halfway with distilled water. Remove a leaf from half an onion and extract a piece of transparent onion peel (epidermis) from the leaf with the forceps. In a watch glass filled with distilled water, place the epidermis.
A vacuole is a cell organelle that is membrane-bound. Vacuoles are tiny compartments in animal cells that assist sequester waste materials. Vacuoles in plant cells assist in maintaining water balance. A single vacuole can sometimes take up the majority of the internal volume of a plant cell.
Vacuoles are simply confined compartments filled with water containing inorganic and organic molecules in solution, including enzymes, though they may also include solids that have been engulfed in some situations. Vacuoles are simply larger versions of membrane vesicles generated by the fusion of several membrane vesicles.
Onion peel cells are rectangular in shape and feature intercellular gaps between them. The cell walls of these cells are different. Large vacuoles are located in the centre of the cells.

Note:
In some animals, vacuoles also play a key role in autophagy, balancing the biogenesis (production) and destruction (or turnover) of various chemicals and cell structures. They also help to lyse and recycle misfolded proteins that have accumulated within the cell.
