Many disease causing bacteria grow in communities using a hydrogel to attach to cell surfaces they infect. This hydrogel is known as a ____
|
|
biofilm
|
|
|
slime mold
|
|
|
intracellular polymer
|
|
|
plasmolipid primer

Explanation:
Detailed explanation-1: -Bacteria are able to grow adhered to almost every surface, forming architecturally complex communities termed biofilms. In biofilms, cells grow in multicellular aggregates that are encased in an extracellular matrix produced by the bacteria themselves (Branda et al.
Detailed explanation-2: -Biofilm formation is a process whereby microorganisms irreversibly attach to and grow on a surface and produce extracellular polymers that facilitate attachment and matrix formation, resulting in an alteration in the phenotype of the organisms with respect to growth rate and gene transcription.
Detailed explanation-3: -Biofilms provide an alternative means for bacteria to attach to surfaces within the body. True.
