How are relationships or interactions between different organelles illustrated? What is missing from this model? Evaluating different models helps learners better appreciate and understand the nuanced ...

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 ...

Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their ...

You probably learned about organelles, those little "organs" inside cells that form compartments with individual functions.

In contrast to organelles with a lipid bilayer membrane, membraneless structures are formed through a process known as liquid-liquid phase separation. When it comes to how and why cells create and use ...

Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized ...

They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no ...

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, ...

Inside of cells, organelles perform specialized functions to keep biological functions moving, one of which is the ribosome. Ribosomes are tiny machines known for making proteins. Another organelle is ...

Textbook drawings of the cell’s largest organelle might need to be updated based on new images. Super-resolution shots of the endoplasmic reticulum reveal tightly packed tubes where previous ...
