Bacteria Morphology Questions

• Gram-positive versus Gram-negative: identify the component likely missing in Gram-positive bacteria Which cell envelope component is characteristically absent from Gram-positive bacteria when compared with Gram-negative bacteria?
• Bacterial flagellar arrangements: flagella distributed all around the cell What is the term for the arrangement in which numerous flagella are distributed over the entire surface of a bacterial cell?
• Mechanism of bacterial flagellar motility By what physical mechanism do bacterial flagella move the cell through a liquid environment?
• Flagellar arrangements at the poles of a bacterium What is the correct term for a flagellar arrangement in which one or clusters of flagella occur at both poles of a bacterial cell?
• Peptidoglycan facts: identify the incorrect statement Which statement about peptidoglycan (murein) is NOT incorrect, i.e., all listed statements are accurate—choose the option that reflects that truth.
• In eukaryotic cells (general cell biology), the cytosolic ribosomes typically sediment at which value on the Svedberg scale?
• In bacteriology, the region where the prokaryotic chromosome is concentrated (without a surrounding membrane) is called the:
• In prokaryotic cytology, which of the following is a true example of a cytoplasmic inclusion (storage/accumulation body)?
• Bacterial morphology: the cocci that most commonly occur as single cells or as paired cells are called:
• Gram stain mechanics: Gram-positive bacteria retain crystal violet primarily because they possess a:
• Which genus comprises bacteria that naturally lack a rigid cell wall, rendering them intrinsically resistant to beta-lactam antibiotics such as penicillin?
• Peptidoglycan assembly: what is the final step in bacterial cell wall synthesis that beta-lactam antibiotics are designed to block?
• Bacterial arrangements: the cocci that characteristically form chains are called:
• Which bacteria lack a rigid cell wall and are therefore intrinsically resistant to penicillin and other beta-lactam antibiotics?
• In cell envelope anatomy, porin proteins are found in which bacterial structure?
• Bacterial motility concept: In microbiology, what does the term “chemotaxis” describe with respect to bacterial movement in the presence of a chemical compound or gradient?
• Endospore-forming genera with medical importance: Which bacterial genera that produce endospores are especially significant in clinical microbiology?
• Cell envelope and external structures: Which bacterial structures are located external to the cell wall?
• Bacterial morphology terminology: What is the common term for bacteria that are spherical in shape?
• Cell wall polymers: Teichoic acids are typically found in which part of bacterial cells?
