Week 4

This week we will learn about mitosis and meiosis. I’m still remembered that when I was in secondary school, I’m also learned about this topic. I’m not understand at all and feel like this topic is very hard and start think why I’m not understand while my friend feel like easy topic. Then, I study hard by doing notes by referring to the textbook and revision book. I also read revision book many times in order to understand well this topic. Now I don’t feel like it is hard topic. The lecturer want to skip this topic because we’re already learn in matriculation, foundation or form six. But Dr still give us brief lecture to refresh this topic.

From part of mitosis, there is cell cycle in eukaryotes which includes interphase and M phase, interphase occupies most of the time in cell cycle which is included G1 phase, S phase and G2 phase. M phase can be separated to some period as prophase, metaphase, anaphase and telophase. After that, we do the SCL Group Activity in Venn diagram to compare and contrast chloroplasts and mitochondria. Our group doing a good job for this task. It’s such fun learning to do it together in group.

Next, our lecturer move to the next topic which is endosymbiosis. This is my first time hearing about it. Endosymbiosis theory is describes about the origin of chloroplast and mitochondria. This theory suggests that mitochondria and plastids in eukaryotic cells were once independent prokaryotic cells. Dr showed us a animation to learn more about endosymbiosis theory. You can find that animation in McGrawHill site. For me, I can find it in putrablast. Then, I reviewed this animation once again because I’m not so focus and understand when Dr gives us the explaination about this topic.

Overall, this week learning is not quiet hard to learn and fun to explore more.
