Caption: Surface of a water fern (Azolla sp.), coloured scanning electron micrograph (SEM). The leaves of water ferns support colonies of Anabaena azollae, a blue-green alga that fixes atmospheric nitrogen and enriches the water in which it grows. For this nitrogen-fixing ability, water ferns are grown in rice paddies in India as a fertiliser plant. The roots are unanchored and are generated by multiple divisions in various planes from just one apical cell. Magnification: x70 when printed at 10 centimetres wide.
