The Microscope and Animal Cells

                In order for us to be able to understand more about the lessons that we have discussed, we are required to do an experiment or a laboratory activity. These experiments/activities helps us to enhance our knowledge the topic that we have discussed. In every chapter that we’ve studied, there are laboratory activities that are needed to be done.

                We started in the chapter about “Animal Cells”. Cells refer to the second level of organization in our body. They are the smallest units of the body that exhibit the characteristics of life. Cells also have different parts like the cell membrane, nucleus, ribosomes and etc. These parts have their certain functions in a cell.
               Our first activity is the “Microscope and Animal Cells”. We were taught on how to use the microscopes. We also discussed the parts and functions of the microscope. After that, we observed the cheek cells. We took a sample from our member and placed it on a glass slide and covered it with a cover slip. We used the microscope in order for us to examine the cheek cells.

                We also observed the three (3) colored little threads using the microscope. The colors of those threads are blue, yellow and red. We compared it on how it looks like before and when we observe it in the microscope.

                The second activity is entitled, “Transport Process”. In the three (3) glass slides, we put one drop of blood each. At the first slide, we added distilled water while at the second slide, we added 0.3% of NaCl and lastly at the third slide, we added 0.9% of NaCl. We compared the cells of each blood samples.

              

               Our last activity in this chapter is Mitosis. Mitosis is the cell division in somatic cells. There are 5 stages in Mitosis, these are the interphase, prophase, metaphase and anaphase. We observed the cells of the fish blastula where we can see the different stages in Mitosis.
