Wood avens seeds. Coloured scanning electron micrograph (SEM) of seeds from a wood aven (Geum urbanum) plant, showing the characteristic hooks. These hooks get caught in the fur of animals enabling the seeds to be carried away from the parent plant, ensuring a long-range distribution of the species. Magnification: x15 when printed 10 centimetres high.
