Question: What are the characteristics of prokaryotic cells?
Answer: 1) they have no nuclear membrane
2) their DNA is not wound around histones
3) the cell walls are made of a chemical called peptidoglycan
4) they do not have complex membrane-bound organelles

Question: The majority of gram-positive organisms have this cell wall structure
Answer: 1) trichroic acid
2) cell membrane
3) peptidoglycan (Murien)
==================================================
Question: The majority of gram-negative organisms have this cell wall structure
Answer: 1) cell membrane

Question: What are the 5 types of flagella?
Answer: 1) Monotrichous
2) Amphitrichous
3) Lophotrichous
4) Peritrichous
5) Atrichous
==================================================
Question: What does monotrichous mean?
Answer: It is a polar cell with a single flagellum on the end of the cell
==================================================
Question: What does Amphitrichous mean?
Answer: Having a single flagellum on both ends of the cell
==================================================
Question: What does Lophotrichous means?
Answer: Has small bunches or tufts of flagella emerging from the same site
==================================================
Question: What does Peritrochous mean?
Answer: Having flagella dispersed randomly over the surface of the cell
==================================================
Question: What does Atrichous mean?
Answer: Without flagella
==================================================
Question: What is a glycocalyx?
Answer: A filamentous network of carbohydrate rich molecules that coats cells
==================================================
Question: What is a slime layer?
Answer: A diffuse unorganized layer of polysaccharides and/or proteins on the outside of some bacteria
==================================================
Question: What is a capsule?
Answer: A hardened slime layer. Most of the bacteria that cause pneumonia make a capsule
==================================================
Question: The nucleus contains this
Answer: DNA
