In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

The endoplasmic reticulum (ER) is a crucial organelle present in all eukaryotic cells, including human cells. The ER plays a ...

1 Despite having been overlooked for the last century, this has turned out to be a prescient description of the interior of eukaryotic cells. In addition to membrane-encased organelles—the nucleus, ...

It's just the way things are. The difference between eukaryotic and prokaryotic cells has to do with the little stuff-doing ...

The structure and function of key prokaryotic cell structures. Prokaryotes have ribosomes but they are smaller and structurally simpler than those in eukaryotic cells. These non-membrane-bound ...

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

“It’s solid science based on a lot of controls.” They also saw that UCYN-A divided in synchrony with other organelles, a piece of data that contributed to their determination that UCYN-A was a true ...
