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

increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase‚ cells serve their specialized functions‚ grow‚ and copy their genetic material. Mitosis is the first stage of cell division‚ in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur‚ the genetic material in each daughter cell is identical to what was
