So, at first, we finished our last lecture about the cell wall of prokaryotes. It can be divided into two which is gram +ve and gram -ve. Gram -ve is more phatogenic compared to gram +ve basically. This picture may show you the difference between them!
| Right-gram +ve || Left-gram -ve |
Based on the type of cell wall of the prokaryotes, we can differentiate either they are gram +ve or gram -ve. We can defintely know the pathogenicity of that prokaryotes depends on their cell wall! I found this table and I hope this can show you a clear differences between them.
Next, we move on to the INTERNAL structures of prokaryotes. The main structures are includes the plasma membrane, ribosomes, nuclear area, cytoplasm, inclusion and endospore. As we come across the content in this topics, we try to imagine all the structures with foods! Hahahaha. For example, the second picture of cell wall above we imagine as spaghetti and meatballs. The peptidoglycan structure we imagine as sausages. Its all because we are hungry ~ ~ ~ ~
Honestly, for 15 minutes before the class ended, I lost my focus because my father arrived at the entrance of the Biotech 1 building to fetch me! But I try to listen what Dr. Wan say in front. As for summary, plasma membrane carries on respiration which is oxidation and reduction process. The Fluid Mosaic Model consists of hydrophilic head (love water) and hydrophobic tail (hate water).
The example of macroelements that getting through the barrier are carbon, oxygen, hydrogen, nitrogen, sulphur, phosphorus, calcium, magnesium and ferum. The liquid part of the cytoplasm is called cytosol. It is jelly-like structure. This is the picture of nucleoid and plasmid.
The longger one which is red in colour is the nucleoid. Both are DNA. Okay, that's all from me now. Have a good day and Selamat Hari Raya Aidiladha to Dr. Wan Zuhainis and all muslims! Take care guys! :)
