Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric ... Learn about our Editorial Policies. Bacteria had grown out in a yellowish smear coating the plates, but ...

In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive organelles, such as micro-compartments found in some bacteria, help organize cellular processes by concentrating ...

researchers contend that what they are seeing may be a snapshot of the evolutionary process of bacterial-derived organelles that are nitrogen-fixing. "Our study focuses on a much more recent ...

Mitochondria — often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That's because these organelles ...

In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is ...

Animal cells contain organelles that are similar to bacterial and unicellular eukaryotic acidocalcisomes, notably the dense granules in human platelets, which contain high concentrations of ...

Some bacteria avoid these inconveniences by instead occupying organelle-like compartments that separate them from the rest of the cell. These microbes can and do still interact with actin—some secrete ...

Mitochondria organelles came from primordial bacterial endosymbionts and still preserve distinct genes for important functions like making ATP. To speed the emerging therapeutic research into the ...
