Question

match the descriptions to the microscope picture they describe:
d
c
b
a
gram + cocci in clusters
gram - bacilli
gram + bacilli
gram + bacilli in chains

Explanation:

To solve this, we analyze each image (A, B, C, D) and match with the descriptions:

Step 1: Analyze Image D

Image D shows spherical (cocci) bacteria grouped in clusters, stained purple (gram +). So D matches "gram + cocci in clusters".

Step 2: Analyze Image C

Image C shows rod - shaped (bacilli) bacteria in chains, stained purple (gram +). So C matches "gram + bacilli in chains".

Step 3: Analyze Image B

Image B shows rod - shaped (bacilli) bacteria, stained purple (gram +). So B matches "gram + bacilli".

Step 4: Analyze Image A

Image A shows rod - shaped (bacilli) bacteria, stained pink/red (gram -). So A matches "gram - bacilli".

Answer:

• D: gram + cocci in clusters
• C: gram + bacilli in chains
• B: gram + bacilli
• A: gram - bacilli
