Animal bodies are hierarchically organised from molecules and cells through tissues, organs and whole systems. Cellular architecture—membranes, cytoskeletons and extracellular matrices—provides ...

Animal cells are far more than simple biological units—they’re dynamic, adaptive, and packed with intricate structures that ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

Volvox parent spheroid: Numerous individual cells can be seen across the entire surface as magenta-colored dots. Developing daughter spheroids appear as a few larger clusters with very small dots. The ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...
