Oleander flower stamen. Coloured scanning electron micrograph (SEM) of the base of a oleander flower (Nerium oleander) stamen. Stamen are a plant's male reproductive structures. They consist of a filament (seen here),which ends in a globular anther. The hairs are thought to be sensory hairs. The stamen produces and releases the male gametes (sex cells),pollen grains. The pollen grains fertilise ovaries,the female gametes. Magnification: x215 when printed at 10 centimetres tall | |
