The ecological diversity of phototrophic bacteria is illustrated by the different ________ that allow them to perform photosynthesis in low light environments such as deep in the ocean, in various sediments, and in thick layered mats.
A) nitrogen fixation strategies
B) bacteriochlorophyll and photosystems
C) specialized stalked cells
D) endospores and resistant cell types

Question

Quizplus · Accepted Answer

Phototrophic bacteria use bacteriochlorophyll and photosystems for photosynthesis, which can vary in structure and function depending on the environment in which the bacteria live. Different types of bacteriochlorophyll and photosystems allow for photosynthesis in low light environments. Choice A (nitrogen fixation strategies) and Choice D (endospores and resistant cell types) are not related to the ability to perform photosynthesis in low light environments, and Choice C (specialized stalked cells) may be seen in some phototrophic bacteria, but not necessarily those adapted to low light environments.
