Here we see just two examples, heart cells (far left) and nerve cells, or neurons. Altogether, multicellular organisms like humans have thousands of differentiated cells. Each is optimized for use ...

contains two distinct cell types and could be the earliest example of complex multicellularity ever recorded, according to the researchers. The fossil offers new insight into the transition of single ...

Credit: Technology Networks. Eukaryotic cells are large (around 10–100 μm) and complex. While most eukaryotes are multicellular organisms, there are some single-cell eukaryotes. 9 Within a eukaryotic ...
