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.

Organelles perform the fundamental processes that help cells (and hence organs, tissues, and organisms) stay alive and operative. In the past several decades, transmission electron microscopy (TEM) ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...

Organelles are small, specialized structures in cells which operate like organs by carrying out specific tasks. The presence of a defined nucleus distinguishes a eukaryotic from prokaryotic cell. It ...

Cell polarity can be defined as a structurally and functionally asymmetric organization, in which the non-random positioning of each organelle, the function of which contributes to cell asymmetry, is ...

The interactions within and between the organelles inside our cells could hold the key to understanding complex diseases such as cancer and neurodegeneration. Recent advances in imaging techniques are ...

video: For the first time, scientists have engineered the complex biological process of translation into a designer organelle in a living mammalian cell. Research by the Lemke group at the European ...
