What structure do onion cells have that make them have a different shape than cheek cells?

Solution

The cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the centre of the cell. It is surrounded by cytoplasm.

As in all animal cells, the cells of the human cheek do not possess a cell wall. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space. The vacuole in an an animal cell is smaller in size, or absent. The nucleus is present at the centre of the cytoplasm.The absence of a cell wall and a prominent vacuole are indicators that help identify animal cells, such as cells seen in the human cheek.

The presence of a cell wall and a large vacuole provides a different shape to the cells in onion peel.
