Third week of class

During week 3, I have learned about cell theory and prokaryotes, eukaryotes, virus, prions and viroids. The class began with SCL activity in groups which are about the cell theory of life such as who has discovered about the cell theory. Every group must give their answer but sadly and regretfully, our group was unable do this task because we cannot access our Putra Blast. We were unable to retrieve the task given by the lecturer as well as the notes about this topic. Prof Madya Dr Parameswari was very upset with us. Though this was mostly due to technical difficulties from Putra Blast, I know I am also at fault here. I will make sure that I won’t do it again.

        In the cell theory of life, I have learned about three basic components of this theory which is all living things are made up of cells. Next, cell is the basic unit of life in all living things. Lastly, new cells arise from the pre-existing cells. I could understand about this cell theory because I have learned this topic during high school and able to refresh my memory again. I am able to remember about the prokaryotic cell structures but the eubacteria cell wall which includes gram-positive and gram-negative cell wall was a new topic for me. Before this, I only got to know their names but now I have learned about the structure. I am very happy to learn about this topic, about the prokaryotes structures such as  nucleoid region, flagella and pilli, endospores, cell membrane and lac operan more deeper. Before the class ended, we did our SCL activity which was drawing the Venn diagram on the similarities and differences between eubacteria and archaebacteria. This activity was very helpful to make students understand better and enhanced their learning towards this topic.

        Next, I have also learned about virus, prions and viroids. Prions is a new topic for me and I rarely heard about this before. So, I was a little bit confused and did not really understand about it. I will try to understand them better by studying the lecture notes. I really enjoyed this topic, cell theory which includes prokaryotes, eubacteria, archaebacteria, virus, prions and viroids.  This topic interest me and I enjoy learning it because I really loves topic relating to cells and this topic is a platform for me to further my study in Master in cell or virus.

so this is one of the shape of the virus

this is the structure of prion

this is the shape of potato that been effected by viroid
