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.
The onion cell is a plant cell and the human cheek cell is an animal cell. The onion cell would have cell wall, vacuole, and granules of starch or oils. The animal cell would â¦ have none of these.he main differences between plant and animal cells are that plant cells have: Animal cells have none of the above.
