Eukaryotic cells are more complex than prokaryotic ones because of specialized organelles. Learn how ancient collaborations between cells gave eukaryotes an important energy boost.

All eukaryotic cells have a cell membrane, also known as a plasma membrane. It consists of a phospholipid bilayer that contains various lipids, membrane proteins and sugars. These are essential for ...

Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth.There are several differences between the two, but the biggest distinction between them is that eukaryotic ...

By contrast, the inside of a eukaryote cell is a bustling metropolis, crowded with a variety of protein factories, control rooms, transportation routes and a central bundle called the nucleus that ...

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed ...

Eukaryotic cell: Prokaryotic cell: Size: Most are 5 μm - 100 μm. Most are 0.2 μm - 2.0 μm. Outer layers of cell: Cell membrane, surrounded by cell wall in plants and fungi.

Scientists have found the first eukaryotic organism that functions fine without mitochondria, the "powerhouses" that make energy for the cells of yeast, humans and other animals.

Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated ...

Researchers in Sweden have pinned down microbes from which all complex life evolved. The microbes have been named Loki, Thor, Odin, and Heimdall, after the gods of Norse mythology.

Milucka said that, within the body of the eukaryote, the bacteria acts similarly to mitochondria in other cells—except instead of using oxygen, it uses nitrate to generate ATP for its host.
