the size of cheek cell and onion cell DCP: Introduction: 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. Hypothesis: 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
