Final answer:
Gram-positive, rod-shaped microorganisms can either produce spores or not. B. megaterium, B. subtilis, B. cereus, and B. amyloliquefaciens are examples of spore-producing species, while C. xerosis, C. amycolatum, and C. bistolyticum do not produce spores.
Step-by-step explanation:
Gram-positive, rod-shaped microorganisms can be categorized into two groups: those that produce spores and those that do not. The microorganisms B. megaterium, B. subtilis, B. cereus, and B. amyloliquefaciens are examples of gram-positive, rod-shaped microorganisms that produce spores. On the other hand, the microorganisms C. xerosis, C. amycolatum, and C. bistolyticum do not produce spores. Spores, in microorganisms, are highly resistant structures that allow them to survive in harsh conditions and can be involved in diseases caused by some bacterial species.
