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 structure and function of slime layers and capsules in bacteria. These are extracellular structures that provide various benefits to the bacterial cell.
Recognize that slime layers and capsules primarily serve as protective barriers. They help in preventing dehydration by retaining moisture around the bacterial cell.
Identify the role of slime layers and capsules in nutrient acquisition. They can trap nutrients from the environment, aiding in the survival of the bacteria.
Consider the function of attachment. Slime layers and capsules facilitate the adherence of bacteria to surfaces and other cells, which is crucial for colonization and biofilm formation.
Evaluate the statement about anchoring the outer membrane to peptidoglycan. Understand that this function is not typically associated with slime layers and capsules, as they are not involved in structural anchoring within the bacterial cell wall.
