Onion cells have large vacuoles in their interior that store water molecules. Cells are arranged in a closely packed way in the onion tissue and hence appear as a brick wall when stained and viewed under the microscope.
My answer on my science paper was that the size shows how much water the cell can hold. The shape: How much water and nutrients the cell can hold. Hope this helped!
because god wanted them to be the same shape as the bricks
Onion cells, like most plant cells, have rigid cell walls which give them a regular shape. They are stacked tightly in columns and rows. Cheek cells have and irregularly shaped cell membrane. and are squished together in layers.
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
No chloroplasts in cheek and onion cells
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
All cells have cytoplasm, so yes, onion cells do have cytoplasm.
they are shaped in the form of a cell wall
The onion cells are much more rectangle shaped, than the cheek cells and the nucleus in the onion cell is much more bigger and better seen in the microscope.
Onion cells are arranged in a closely packaged way. This is so that they layers of the onion can be thick and tough.

All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.
No chloroplasts in cheek and onion cells
Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.

A onion cell is : 0.2 mm
