Do archaea conduct photosynthesis

Answer 1

Yes, some archaea are capable of photosynthesis, but their mechanisms differ from those in plants and some bacteria. For instance, certain halophilic archaea, like Halobacterium, use a pigment called bacteriorhodopsin to capture light energy and convert it into chemical energy, rather than using chlorophyll. This form of photosynthesis is called "bacteriorhodopsin-based phototrophy" and is distinct from the oxygenic photosynthesis seen in plants. Overall, while not as common as in other domains of life, photosynthesis does occur in some archaeal species.
