To summarize: The structures observed in bacterial cells and their molecular makeup.
Introduction: Eukaryotes, Archaea, and eubacteria are the three domains of life. Eukaryotes consists of the majority of organisms namely, animals, plants, and fungi. Eubacteria composed of all true bacteria and archaea composed of primitive bacteria.
Explanation of Solution
The bacterial cells composed of a peptidoglycan layer, which is an outer layer present outside the plasma membrane. In gram-negative bacteria, the peptidoglycan is thinner, while in gram-positive bacteria, it is thicker. The peptidoglycan is made up of N-acetylmuramic acid (NAM) and N-acetyl glucosamine (NAG) alternating residues that confer protection to the cell. It also includes locomotory organs (like flagella), receptors, and virulence factors. A lipid bilayer is also present in the bacterial cell.
The molecular makeup of bacterial cell is well-defined by their macromolecules. The molecular makeup of bacterial cell includes macromolecules like proteins, phospholipids, polysaccharides, lipids, and
