Cheek cells, being animal cells, do not contain a cell wall as onion â¦ cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do.
Onion cells. 1  1. ONION CELLS. 2  2. ONION PLANT This is what a whole onion plant looks like. We will be looking at cells from the onion bulb. 3  3. Copy CELL WALLPlant cells have cell walls.â¢ Cell walls are made up of cellulose.â¢ They protect the cell.â¢ Maintains the cells shape.â¢ Prevents excessive water uptake. When staining your onion cell, you will need to wait a minute or two before viewing it under the microscope. The stain can take some time to sink in to the cells because of the barrier that the cell wall creates.
