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, and lysosomes.

The cellular life cycle, also called the cell cycle, includes many processes necessary for successful self-replication. Beyond carrying out the tasks of routine metabolism, the cell must duplicate its ...

All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start.

Eukaryotes—fungi, plants, us—are complex. Our large cells are characterized by their different compartments, many of which are neatly enclosed within a boundary of membrane. These compartments contain ...

The origin of complex cells started without oxygen, new research suggests. Since the 1960s, many experts have argued that the emergence of eukaryotes (cells containing a clearly defined nucleus) ...

We’ve all seen the popular cartoon of evolution’s march from an ancient sea, beginning with a single floating cell that morphs into increasingly complicated creatures, on the way to the punch line of ...

What separates animals, plants, fungi and even amoebas from bacteria? Well, there's one feature that no longer universally makes us distinct, thanks to a new study that redefines what it means to ...
