What most of the plant cell is composed of by volume; a large central vacuole.
vacuole.
Plant cells possess large size vacuoles as plant cell vacuoles are full of cell sap and provide turgidity and rigidity to the cell. Many substances of importance in the life of the plant cell are stored in vacuoles. The central vacuole of some plant cells may occupy 50 - 90% of the cell volume
A plant cell contains a water vacuole that contains water and other nutrients. The plant is wilted when the water vacuole is not expanded. Thus the plant is in a normal condition when its cells' water vacuoles are full of water and other nutrients.
The central vacuole is in the plant cell.
In certain cases, a vacuole can occupy up to half the volume of the entire cell
The vacuole occupies most of a typical plant cell's volume. It is basically a pocket filled with water containing molecules.

vacuole.
That sounds like the large central vacuole of mature plant cells.

because Onion is a plant. Plant cells have a large vacuole in the centre of the cell which push the surrounding organelles and the nucleus towards the periphery. On the contrary, if you observe an animal cell you will find that the nucleus is situated right at the center because the vacuole is small comparatively and does not occupy a large space at the center.
makes up 90% of internal volume of the cell
