(A) Young Volvox adult, with about 2,000 small somatic cells in a monolayer at the surface, and nineteen large gonidia embedded in the extracellular matrix (ECM), just under the somatic cell layer.

Many different types of cell, including sperm, bacteria and algae, propel themselves using whip-like appendages known as flagella. These protrusions, about one-hundredth of a millimetre long ...

Algae colonies, such as the Volvox one shown here, are propelled through water by the coordinated movements of their whip-like flagella. If you're enjoying this article, consider supporting our ...

MICROSWIMMERS MAKE A SPLASH | Two colonies of Volvox algae orbit each other in a waltz caused by the coordinated strokes of hundreds of tiny undulating flagella.

The swishing actions of tiny swimming organisms play a key role in distributing heat and nutrients throughout the world’s oceans and lakes, but these mixing effects are more complicated than we first ...

Flagellum failure lets bacteria turn Buckling of appendage drives tiny two-point turn TINY RUDDER Over the course of 90 milliseconds, a bacterial cell (Vibrio alginolyticus) makes a hard right turn.

The best studied flagellum, of the E. coli bacterium, contains around 40 different kinds of proteins. Only 23 of these proteins, however, are common to all the other bacterial flagella studied so far.

This ball of two thousand cells is the embryo of a tiny organism called volvox. It’s about to turn itself inside out. Physicists and biologists at Cambridge University used an advanced kind of ...
