All are found within Gram positive cells (4) Which of the following is not found in Gram negative cells? a. Outer membrane b. Cell membrane c. Lipopolysaccharide (endotoxin) d. Peptidoglycan e. All are found within Gram negative cells (5) True or False, Bacteria and Archaea are two evolutionarily distinct domains that both contain prokaryotic organisms 6) Which of the following structures is not found in both prokaryotic and eukaryotic cells? Dcell membrane flagella dnucleus 7) which of the following means of motilityare used by eukaryotic cells but not prokaryotic cells a. Flagella b. Cilia c. Pseudopodia d. All three are used by both e. B and C are used only by eukaryotes f. A and C are used only by eukaryotes (8) True or Failse, penicillin is most active on the static peptidoglycan found within non-replicating Gram positive cells.Explanation / Answer
3. All are found within Gram positive bacteria. A gram positive bacteria, possess outer membrane and cell membrane; peptidoglycan and techoic acid in their cell wall.
4. All are found within gram negative cells. A gram negative cell consists of cell membrane and outer membrane along with peptidoglycan and endotoxin.
5. True, both archae and bacteria are evolutionary distinct but prokaryotes. Compared to bacteria, archae has an entirely different biochemical composition and evolutionary history.
7. B and C are used by eukaryotes. Pseudopodia are considered as a temporary cytoplasmic projection or out growth in eukaryotic cells. Cilia are protruding from eukaryotic cells.
8. True, penicillin affects the gram positive bacteria which do not contain protein and lipopolysaccharides in peptidoglycan layer of the cell wall, like gram negative bacteria.
