Prokaryotic Community Structure and Metabolisms in Shallow Subsurface of Atacama Desert Playas and Alluvial Fans After Heavy Rains: Repairing and Preparing for Next Dry Period ...

Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell ...

Bacterial cells Researchers have also detected biomolecular condensates in prokaryotic, or bacterial, cells, which traditionally were defined as not containing organelles.

In two recent papers, an international team led by UC Santa Cruz scientists describe the first known nitrogen-fixing organelle within a eukaryotic cell. The organelle is the fourth example in history ...
