One of these involves fusion between cells from domains Archaea and Bacteria ... Like Cell Biology of a Bacterium Planctomycete cell structure differs from that of all other known prokaryotes.

Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists ... that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane ...

Scientists know relatively little about archaea compared to their bacterial counterparts ... “Is there any direct interaction with human cells, like epithelial cells of the gut?” Albers wondered.

“If we keep looking for defense systems in Archaea through homologs of already described ones in bacteria, we won't find them.” Buzz Baum, a cell biologist studying archaea at the Medical Research ...
