During this week (7-11 September), in biology class we start the class on Monday by continuing in discussing about mitosis in cell cycle, starting from the anaphase. After the anaphase, there is the last step of mitosis which is telophase. I learned from the steps of mitosis that mitosis happens when centriole starts to appear and going to separate direction and the nuclear membrane broke. As the dan floats in the cytoplasm, the pairs of chromosome attach to the spindle fibers connected to the centriole. Then the pair of chromosome separate and two nuclei start to appear as the chromosome appear as the chromatin. Then during cytokinesis phase in cell cycle, the cell formed new nucleus and divides itself. After that, we also learned about the process of photosynthesis and cellular respiration. Their relation is that photosynthesis is used by plants to make food in a form of glucose and later the glucose is used in cellular respiration to produce ATP energy in the mitochondria that is used for active transport. On Tuesday, in biology class we continue learning more about cells. We learned about types of cell in the body such as red blood cells, nerve cells, bone cells, sperm cells, epithelial muscle cell, skeletal muscle cell and others. We also learned about the difference between cells, tissue, organ, system and organism. Tissue is a group of cells working together, organ is a group of different tissue working together, system is a group of different organs working together and organism is a group of different systems coordinated to carry out some function. After that, we were told to make our cheat sheet for the summative assessment on Monday. On Friday, in biology class we did a review for Monday's summative. I get to ask the question about what I'm still confused about, which is the more detailed cellular respiration. I learned that cellular respirations happens in mitochondria to make ATP that stands for Adenosine Triposphate, Mitochondria also produce waste in a form of water and carbon dioxide. In cellular respiration, the atom C6 will break into two, and then C3 is equal to two ATPs. In the ATP, there is three phosphate, and later one phosphate is given to cell membrane for active transport, while the other two phosphates will return because the phosphates has to be in a pair three. I'm kinda still confused about it, but I decided to add it in my list of what-to-learn for the summative along with microscopes and how prokaryote organelles work together.
