Bee orchid seed. Coloured scanning electron micrograph (SEM) of an Orchid seed. Coloured scanning electron micrograph (SEM) of seeds from a bee orchid. Due to their small size, the seeds of orchids lack the endosperm (nutrient tissue) necessary for successful germination. Orchids are therefore dependent on a symbiotic relationship with fungi whereby the embryos germination is initiated by the penetration of fungal hyphae into the seed. The embryo gains nutrients by digesting part of the fungal body and excretions from the fungus. Because of their small size orchid seeds are dispersed by being carried on the wind. Bee orchid (Ophrys apifera), a perennial herbaceous plant. It is an example of floral mimicry and sexual deceptive pollination. It is widespread across central and southern Europe as well as North Africa and the Middle East. Magnification: x80 when printed at 10cm wide.
