Which of the following is not a function of slime layers and capsules:
A
Protection against dehydration.
B
Collect nutrients from its surroundings.
C
Attachment to other cells & solid surfaces.
D
Anchors the outer membrane to peptidoglycan.
Verified step by step guidance1
Understand the role of slime layers and capsules in bacteria. These structures are primarily composed of polysaccharides and sometimes proteins, forming a protective layer outside the cell wall.
Recognize that one of the main functions of slime layers and capsules is to protect bacteria from environmental threats, such as dehydration, by retaining moisture.
Identify that slime layers and capsules also facilitate the attachment of bacteria to surfaces and other cells, which is crucial for forming biofilms and colonizing environments.
Consider the role of slime layers and capsules in nutrient acquisition. They can trap nutrients from the environment, aiding in the survival of the bacteria.
Evaluate the statement 'Anchors the outer membrane to peptidoglycan.' This function is typically associated with the cell wall structure, not the slime layer or capsule, indicating it is not a function of these structures.
