Assalamualaikum, Hi!
Not long ago, in Microbiology classes, we have finished yet another topic which is the Prokaryotic Cells. The classes were interesting where we did a lot of activities such as combine-mind-mapping and we also did a self-evaluation on our own understanding on prokaryotic cells in Quizlet. To be frank, I think Quizlet is kind of weird.It is either that or it's me that don't know how to use it properly yet. Anyway, I have learned a lot for a week about prokaryotes.
Prokaryotes are organisms that have no nucleus like bacteria and archaea. I have learned how to compare a prokaryotic cell and eukaryotic cell as shown below:
There's also nucleiod which is a localised genetic material, axial filaments and glycocalyx for protection against dehydration, source of nutrient, and attachment to surface.Prokaryotes also have many types of inclusion such as metachromatic granules, polysaccharide granules, lipid inclusion , sulfur granules, carboxysomes, gas vacuoles and magnetosomes. Each inclusion functions differently. For example, gas vacuole is for buoyancy while lipid inclusion is for lipid storage.The plasma membrane of prokaryote are much similar to eukaryote which are made up of phospholipid bilayer, proteins and carbohydrates like glycolipid and glycoprotein .
Other than that, I have learned that bacteria can be classified based on their Gram Staining which is Gram Positive and Gram Negative.The cell wall of these bacteria are structured differently as shown bellow:
I really enjoyed the classes this week and can't wait for next week.
Adios~
