Week 3

This week I’m gonna discover about the topic discovery of cell which is cell theory and prokaryotic cell and virus together with that is certain new topic which I never heard before like prions and viroids. I’m tried to make a revision about this topic before Dr give us lecture. But it seem like I don’t quiet  understand about this topic. Certain topic like theory of cell, eukaryotic cell and prokaryotic I’ve already learn in Microbiology class.

So, I can remember these part especially scientists who gave a great contribution for discovery of cell like Robert Hooke who start the invention of microscope in 1660s, discovered cell while looking through a slice of cork and had described cell as tiny boxes/honey comb while his book Micrographia describes the microscopic world, Anton van Leeuwenhoek who used his made microscope to view sample from pond and discovered single cell organisms, Schleiden & Schwann had made a theory that all living things is made up of cell, Virchow through his theory of cell division and theory spontaneous generation had proven by Louis Pasteur. These scientists was a great people for these discovery and I cannot imagine how they can discover about these. Then, Dr Parames show us a video about Wacky History Of Cell Theory. I can learn and know more about this topic. Thank you Dr.

In this topic, we also learn about modern cell theory, capsules/slime layer, bacterial and archae cell membrane, nucleoid region, flagella and pilli, endospores, plasmids, reproduction and metabolism. New thing for me to learn is prions which is an infectious agent that is composed primarily in protein, prion protein, and prion disease. The second is viroid which is small circular RNA molecules without protein coat and usually infect the plant. These think is unique right?

Then, we do SCL Group Activity which is create a Venn diagram that illustrates the similarities and differences between eubacteria and archaebacteria during the class session. It’s a good idea for us to work in group and try to finish on time. We actually gain more knowledge because we do some research in many websites include youtube while doing this exciting activities. By doing this, actually we have learn the knowledge because of course we read the information while surf the internet right? After that, we also had being given SCL Group Activity about Introduction to Cells and Cell Theory to do together in group. We had divided the task who gonna do this, this and this. I do the part similarities and differences between eukaryotic and prokaryotic cell. I searched these information in the internet and notes.

Lastly, I’m very enjoy the part that we had to do Venn diagram. And everyone seem like very happy and enjoy as well. Learning is not just come up from read the notes but also in other way like doing mind map, activities, do some research in library, search in internet and etc. We have to take a chance to accept this way in our learning process.
