What initiates the process of spore germination after dormancy?
Understand the Problem
The question is asking about the specific factors that trigger the beginning of spore germination after they have been dormant. We need to identify the correct option that explains this initiation process.
Answer
Exposure to molecules like amino acids, sugars, and muropeptides initiates spore germination after dormancy.
The process of spore germination after dormancy is initiated by exposure to specific molecules such as amino acids, sugars, and cell wall muropeptides that bind to receptors in the inner spore membrane.
Answer for screen readers
The process of spore germination after dormancy is initiated by exposure to specific molecules such as amino acids, sugars, and cell wall muropeptides that bind to receptors in the inner spore membrane.
More Information
Spore germination involves the reactivation of dormant spores, often triggered by environmental signals. These triggers bind to specific receptors that activate pathways, leading to the rapid emergence of a growing cell.
Tips
A common mistake is to overlook the importance of specific molecules acting as triggers rather than just general nutrients.
