Explanation:

To solve this concept map about bacterial stains, we analyze the relationships between stain types:

1. Top - level Classification (Bacterial Stains branches):

• Stain the specimen: These are Positive stains (they color the bacterial specimen, not the background).
• Stain the background: These are Negative stains (they color the background, leaving the specimen unstained).

2. Positive Stains Sub - branches:

• Easy identification of shape and arrangement: Simple stains (basic stains that highlight cell morphology).
• Distinguishes organisms: Differential stains (separate bacteria into groups, e.g., Gram - positive/Gram - negative).
• Illustrates certain structures: Special stains (target specific structures like capsules, flagella, or acid - fast cells).

3. Differential Stains Sub - branch:

• Determines presence of LPS layer: Gram stain (LPS is in Gram - negative bacteria; Gram stain differentiates based on cell wall structure, including LPS presence).

4. Special Stains Sub - branches:

• Defines means of motility: Flagellar stain (stains flagella, which are involved in motility).
• Other special stains: Capsule stain (stains capsules) and Acid fast stain (stains acid - fast bacteria, e.g., Mycobacterium).

Filling the Boxes (from top to bottom, left to right):

1. (Stain the specimen box): Positive stains
2. (Stain the background box): Negative stains
3. (Distinguishes organisms box): Differential stains
4. (Easy identification of shape and arrangement box): Simple stains
5. (Illustrates certain structures box): Special stains
6. (Determines presence of LPS layer box): Gram stain
7. (Defines means of motility box): Flagellar stain
8. (Negative stains sub - box): Capsule stain (or Acid fast stain, but Capsule stain is a common negative - type special stain; alternatively, the negative stains sub - box under “stain the background” would be filled with a negative stain - compatible term, but since Capsule stain can be a negative stain for capsules, it fits here. However, the main negative stain category is “Negative stains” at the top, and the sub - box under it would be a specific negative stain, like Capsule stain (as it stains the background around the capsule).

Final Mapping (Key Placements):

• Bacterial Stains → (left) Positive stains; (right) Negative stains
• Positive stains → (left) Differential stains; (middle) Simple stains; (right) Special stains
• Differential stains → Gram stain (determines LPS layer)
• Special stains → Flagellar stain (defines motility); also includes Capsule stain, Acid fast stain
• Negative stains → Capsule stain (stains background around capsule, so specimen (capsule) appears unstained against stained background)

(Note: The exact placement of “Capsule stain” and “Acid fast stain” may vary slightly, but the above logic follows the principles of bacterial staining: Positive stains color the cell, Negative stains color the background; Simple stains show shape, Differential stains distinguish groups, Special stains target structures.)
