Question

1. which of the following terms refers to a bacterial cell having a single tuft of flagella at one end? (0.5pts)

□ monotrichous
□ amphitrichous
□ peritrichous
□ lophotrichous

1. bacterial cell walls are primarily composed of which of the following? (0.5pts)

□ phospholipid
□ protein
□ carbohydrate
□ peptidoglycan

1. which of the following organelles is not part of the endomembrane system? (0.5pts)

□ endoplasmic reticulum
□ golgi apparatus
□ lysosome
□ peroxisome
(and part of another question is visible on the left edge)

Explanation:

1. Monotrichous means a single flagellum at one end; amphitrichous has flagella at both ends; peritrichous has flagella all over; lophotrichous has a single tuft at one end.
2. Bacterial cell walls are uniquely made of peptidoglycan; phospholipids are cell membrane components, proteins/carbohydrates are present but not the primary cell wall material.
3. The endomembrane system includes endoplasmic reticulum, Golgi apparatus, lysosomes; peroxisomes are separate organelles not part of this system.

Answer:

1. Lophotrichous
2. Peptidoglycan
3. Peroxisome
