microbiology - Why are there no known photosynthetic archaea?


I'm taking a microbial physiology course and we noted that, while some archaea are phototrophic, there are no known photosynethetic archaea.

The title is the question. If additional specificity is needed I will add clarification here. Are there any multicellular forms of life whic...
