In your own words, describe in two paragraphs, the following bacterial cell wall characteristics related to gram-positive strains and gram-negative strains: (a) chemical composition, (b) resistance to phagocytosis, and (c) decolonization by alcohol during gram-staining (d) sensitivity to antimicrobial agents. Peptidoglycan (pep-tid-o-gly-can) is a molecule found only in the cell walls of bacteria its rigid structure gives the bacterial cell shape, surrounds the plasma membrane and provides. And lastly, the bacterial cell wall can contribute to the pathogenicity or disease –causing ability of the cell for certain bacterial pathogens structure of peptidoglycan let us start with peptidoglycan, since it is an ingredient that both bacterial cell walls have in common.

The study of the bacterial cell wall dates back to more than five decades when salton and home (1951) described the structure of cell wall for the first time this was later confirmed by electron microscopic studies. Structure and function of bacterial cells (page 5) structure of the gram-positive bacterial cell wall the wall is relatively thick and consists of many layers of . Even though both archaea and eubacteria have a cell wall to maintain rigidity throughout the cell, there areshow more content although both archaeal and bacterial cells possess flagella for motility, the composition of each organism’s flagellum is very different.
Essay on biology: bacteria and chromosomes diploid- cells respond to stimuli 4 reproduce to pass on genes genes are segments of dna that include the instruction manuals for producing proteins, which determine a particular trait by controlling our metabolism (all the chemical reactions that happen in a cell) dna controls the structure, function and organization through protein synthesis dna is . Cell wall: what is the chemical composition of the bacterial cell wall be able to diagram the cell wall showing the repeating polysaccharide units and location of the peptide cross bridges (not detailed, just m + g and where the crosslinks are). The ability to characterize bacterial cell-wall composition and structure is crucial to understanding the function of the bacterial cell wall, determining drug modes of action and developing new-generation therapeutics. The cell wall provides shape to the cell and protects the bacteria from changes in the osmotic pressure peptidoglycan (murein) is the principal component of the bacterial cell wall and it is responsible for the shape and extreme tough nature of the cell wall. Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation for example, a relatively thick, meshlike structure that makes it possible to distinguish two basic types of bacteria.
