When bacteria are exposed to nutrient-poor conditions,they form thick-walled structures that contain the chromosome and a small amount of cytoplasm.These structures are called
A)plasmids.
B)pseudomonades.
C)nucleoids.
D)endospores.
E)exospores.

Question

Quizplus · Accepted Answer

The description fits that of endospores, which are formed by certain bacteria when nutrients are scarce. They contain the bacterial chromosome and a small amount of cytoplasm, and are enclosed in a thick protective wall. Plasmids are small, circular DNA molecules found in many bacteria, but they do not form structures like endospores. Pseudomonades are a group of bacteria within the genus Pseudomonas. Nucleoids are regions within the cytoplasm of bacterial cells where the chromosome is located. Exospores are not a commonly-used term in microbiology, and may refer to structures produced by certain fungal or plant cells rather than bacteria.
