cell wall and membrane structure of procaryotes

Hi guys !
today we just continue with the subtopic two which is cell wall and membrane structure of procaryotes. What we learn from this topic also had been taught on lecture from previous semester.Briefly whats important part in this topic are: structure and function of cell wall and membrane structure like glycocalyx, flagella, axial filaments, fimbrae and pili.

Dr wan also taugh us the comparison and contrast of cell wall between Gram +ve bacteria and Gram -ve bacteria.
Here is the website that will help our understanding on gram positive and gram negative bacteria differences.

but there is bacteria with Atypical cell wall such as Mycoplasma(small bacteria)

·         no wall or little wall material

·         sterol give rigidity to membrane

·         can pass through bacteria filter

besides that, another important thing is the gram + and gram - archae . i con conclude the comparison of gram + and gram - bacteria as:

                                                            Gram +archae                    gram –archae
