Structure of eukaryotic cells Eukaryotic cells generally contain several membrane-bound organelles, including the nucleus, mitochondria, the ER, the Golgi apparatus and lysosomes (Figure 1). Plant ...

What is a prokaryotic cell? Prokaryotes are small, single-celled organisms with a simple structure. Unlike other cells, they don’t have a nucleus or other membrane-bound organelles. Instead, most ...

Thanks to cryo-electron tomography, a state-of-the-art imaging technique that flash-freezes cells to capture them in 3D with near-atomic resolution, scientists were able to observe the hemifusome.

The origin of these microtubules has been unclear -- until now. In a newly published article in Cell , the ETH researchers discovered related structures in Asgard archaea and describe their structure.

Membrane-bound organelles were the textbook standard of how scientists thought cells were organized until they realized in the mid-2000s that some organelles don't need to be wrapped in a membrane.

The 'cell of origin' of the second most common lung cancer and the way that it becomes dominant in the lung have been discovered, in a new study in mice and humans from researchers at UCL, the ...
