My Ambition Essay

QUEST TO KNOWING CELLSStains are used to improve the contrast of the specimen so that the cells can be easily seen using the light microscope. Staining can damage the cells and possibly kill them; the nature morphology may be altered. The cheek cell should be scraped off gently to avoid damaging and crushing the plasma membrane and only two or three times to avoid injury to the cheeks. (Anonymous, 2011) Human cheek cells- no fixed shape, no cell wall, vacuoles absent, generally smaller in size, not arranged in a fixed pattern. Onion epidermal cells- fixed shape, cell wall, vacuoles present, generally bigger in size, arranged in a regular pattern. (Gan, 2009)Cells must be discussed appropriately and accurately. The epidermal cells of onions and human cheek cells cannot be seen by the unaided eye but can be seen under light microscope. For total magnification of x100, the onion and cheek cells appear to be very small with the nucleus slightly visible. As the magnification increases, the cells become clearer and the structure of the onion and cheek cells can be compared. Many cells appear quite transparent under microscope and are quite difficult to see. By staining the onion and cheek cells, a better contrast is provided so that the cells can be observed clearly and the shape, size and structure of the cells can be determined easily.While observing the slide containing the onion cells, it is noticed that the onion cells have a regular shape. They are generally rectangular in shape as each cell is surrounded by a cell wall. The cell wall is made of cellulose and forms much of the supporting framework of the cell. Each cell also has a prominent nucleus, a large vacuole and the cytoplasm surrounding the vacuole. The nucleus is slightly pressed against the inner side of the cell wall. It is contained in the cytoplasm and is pushed against the cell wall by the large, fluid-filled vacuole.Cheek cells are epithelial cells that line the interior surface of our mouth. Under high power of the light microscope, the nucleus can be seen clearly as it is darkly stained by the methylene blue solution. Also, a pale blue cytoplasm can be seen in each cell but there is no large central vacuole or cell wall as observed in the onion cells. Each cheek cells is surrounded by a plasma membrane. However, other organelles in onion and cheek cells such as RER/SER, mitochondria, Golgi apparatus, etc cannot be seen under the light microscope.This introduces us to more cells starting from the beginning. The cell theory states that… New cells are formed by the division of pre-existing cells. Cells contain genetic material which is passed on from parent to daughter cells. All metabolic reactions take place inside the cells. Prokaryotic cells… such as bacteria whereas eukaryotic cells… such as plant cells and animal cells.Generally, the living component of a cell is called the protoplasm which consists of the...
