A) Endospore formation,low-nutrient stress,endospore germination,breakdown of parent cell
B) Low-nutrient stress,endospore formation,breakdown of parent cell,endospore germination
C) Endospore formation,endospore germination,breakdown of parent cell,low-nutrient stress
D) Low-nutrient stress,endospore germination,breakdown of parent cell,endospore formation
E) Endospore germination,breakdown of parent cell,low-nutrient stress,endospore formation

Question

Quizplus · Accepted Answer

Gram-positive bacteria form endospores in response to low-nutrient stress. Once the endospore is fully formed, the parent cell breaks down, and the endospore remains dormant until conditions improve. When conditions improve, the endospore germinates, and a new vegetative cell is formed. Therefore, the correct chronological order is low-nutrient stress, endospore formation, breakdown of parent cell, and endospore germination. Option B is the only one that follows this sequence.
