OBSERVING ANIMAL AND PLANT CELL UNDER LIGHT MICROSCOPE INTRODUCTION Today I am going to examine cell examples that are taken from the cheek and plant cell under a light microscope. By this way I will be able to see the differences between animal cell structure and plant cell structure. I don’t expect to see any cell wall, chloroplast and large vacuole in animal cell, but I expect to see only a cell membrane and centriole. For the plant cell I think I am going to see a cell wall, vacuole and chloroplast. DESIGN Apparatus Plant Cheek cell sample Light microscope Slide Slip cover Methylene blue Iodine solution Pipette PROCEDURE Firstly, I took a light microscope by holding it from its arm and base. Then I took a sample from my cheek and put it on to the slide. I dropped water on to the sample by using pipette. As I wanted to see the sample clearly, I dropped out some methylene on to the slide and I covered the slide with a slip cover. Finally, I placed the sample on the stage to examine the cells. By using an ocular lens that has a magnification with 6 X and objective lenses with 10 X and 40 X. After I found the cell under the microscope I used objective lenses to get a more clear and detailed seen. Lastly, I drew what I saw under the light microscope. For the second time I observed a plant cell. I took a sample from a plant leaf. I dropped some water on to the slide then I put the sample on it. After that I added iodine solution on to the plant sample. Lastly, I covered slide with a slip cover and started to examine the cells by using ocular lens that has a magnification with 6 X and objective lenses with 10 X and 40 X. As I did in animal cell examination, I used ocular and objective lenses to get more clear and detailed seen. Finally, I again drew what I saw under the light microscope. CONCLUSION As I stated in introduction part, I expected to see organelles inside the cells, but I could not be able to see the organelles, because I used a light microscope in my experiment. For animal cell, I was only being able to see the cells’ nucleus, membrane and cytoplasm. For the plant cell, I only saw membrane, cell wall, cytoplasm and nucleus. As a conclusion, I understood that I examined two eukaryotic cells. MUHAMMED AYDIN
