Structural part of the cell wall of most bacteria. Composed of polysaccharide chains containing repeat units of N-acetylmuramic acid and N-acetylglucosamine, cross-linked by short chains of amino acids. Correct Answer-Peptidoglycan Found only in the outer membrane of gram-negative cells; lipid A is the active component; they are also called endotoxin. Correct Answer-Lipopolysacharides This gelatinous, sticky substance is usually composed of polysaccharides or proteins that surround the out...

Endosymbiosis Ans: Organelles originated when a single-celled organism engulfed another single-celled organism • Usually obligate: the survival of one depends on the other the process in which unicellular organisms engulf other cells, which will then function as organelles within the host cell. Studies of DNA sequencing suggest that green and red algae developed when heterotrophic eukaryotes engulfed cyanobacteria. Algae Ans: -Eukaryotic • Aquatic • Photo-autotrophs • Unice...
