Question

A bacterial species is discovered that contains thylakoids and carboxysomes. It can be assumed from the presence of these structures that this bacterium Choose one: A. is capable of photosynthesis. B. can attach to a nonliving substrate. C. can orient along Earth’s magnetic fields. D. is pathogenic.

Answer 1

A. Bacterium is capable of photosynthesis.

Step-by-step explanation:

Thylakoid is the membrane bound structure where light dependent reaction of photosynthesis occurs. Thylakoid is present in chloroplast and cyanobacteria.

Carboxysomes are the compartments that are involved in carbon fixation.

So if a bacteria contains thylakoid it can perform light reaction of photosynthesis (ATP, NADP production) and If it also have carboxysomes it can also perform dark reaction of photosynthesis (Carbon fixation).
