Question

question 1
what is the gram nature and morphology of this organism in the picture?
○ gram negative coccus
○ gram negative bacillus
○ gram positive coccus
○ gram positive bacillus

Explanation:

1. First, recall Gram - staining principles: Gram - positive bacteria retain the crystal violet stain (appear purple), and Gram - negative bacteria appear pink/red after counter - staining. In the image, the bacteria are purple, so they are Gram - positive.
2. Then, analyze morphology: Cocci are spherical, bacilli are rod - shaped. The bacteria in the image are spherical (coccus - shaped). So combining these two observations, the organism is Gram positive coccus.

Answer:

C. Gram positive coccus
