Hooked fruit of goosegrass
Numéro d’image : 11539990
| False colour scanning electron micrograph showing 2 barbs on the surface of a hooked fruit of cleavers or goosegrass,Galium aparine,entangled in Shetland wool. Commonly known as a bur,the fruit contains a single seed,which is dispersed by means of the barbs covering its surface. The barbs attach to animal fur or human clothing & are transported for some distance before being removed. The fruit may also pass undamaged through the digestive system of some animals. The synthetic material used in the clothing industry as a fastener,is based on the same principle as the hooked fruit. Magnification: X 57 at 35mm size. original is BW print b790/010 | |
