Compare the size of cheek cell and onion cell


In this experiment, Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell.

The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain the size of it while animal cell doesn’t. Also, plant cell usually has a large vacuole and chloroplast, therefore it should be larger than an animal cell. The estimate size of plant cell is between 300µm too 500µm1, animal cell

- Rounded in shape
- Smaller than onion cell (Allium cepa)

After all the investigation, it proves that plant cell has a larger size than animal cell.
As the graph show, the sizes of Homo sapiens are quite regular while Allium cepa have quite extreme size. The smallest size of Allium cepa is 230µm and the biggest is 600µm their difference is 370µm. Homo
