(Phys.org)—A team of researchers with Delft University in the Netherlands has found via lab experiments, that synchronization that occurs with algae flagella while they swim is likely not driven by hydrodynamic forces. ...
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, function like tiny oars, helping ...
