Question

match the following extracellular layers of a bacterial cell according to their relationships.
① instructions
capsule
slime layer
s - layer
disorganized protein layer organized protein layer
disorganized sugar layer organized sugar layer

Explanation:

• Capsule: Bacterial capsules are structured, organized layers made of sugars (polysaccharides), so it matches "organized sugar layer".
• Slime layer: The slime layer is a less structured (disorganized) layer composed of sugars, so it matches "disorganized sugar layer".
• S - layer: The S - layer in bacteria is a protein - based layer. It can be organized (in some cases) or disorganized, but typically the S - layer is an organized protein layer, and the other option for protein is disorganized. The S - layer is known for its organized structure, so it matches "organized protein layer" (or if considering the other protein option, but the key is the composition: capsule and slime layer are sugar - based, S - layer is protein - based. So capsule is organized sugar, slime is disorganized sugar, S - layer is organized protein (or the disorganized protein would be a misfit, so the correct matches are based on composition: capsule - organized sugar, slime - disorganized sugar, S - layer - organized protein (assuming the options are as given: disorganized protein, organized protein, disorganized sugar, organized sugar).

Answer:

• Capsule $\longleftrightarrow$ organized sugar layer
• Slime layer $\longleftrightarrow$ disorganized sugar layer
• S - layer $\longleftrightarrow$ organized protein layer
