Microbiology: Chapter 4 True/False Flashcards

1) The cell walls of bacteria are responsible for the shape of the bacteria and the difference in the Gram stain reaction.

2) Antibiotics that target the cell wall are an effective treatment against many pathogenic bacteria.

3) Cells placed in a hypotonic solution tend to lose water due to osmotic pressure.

4) Small, hydrophobic molecules pass through a cell membrane most easily by diffusion.

5) Spheroplasts, protoplasts, and mycoplasms are bacterial cells without cell walls.

6) Endospores are a reproductive structure.

7) The internal structure of eukaryotic cilia and flagella are the same.

8) Many enzymes in both prokaryotic and eukaryotic cells are compartmentalized within organelles.

9) The number of organelles such as chloroplasts, mitochondria, and rough endoplasmic reticulum is the same in all eukaryotic cells.

10) If you observe rod-shaped red cells after the Gram stain, you can assume their cell walls contain endotoxin.
