Oleander flower anthers. Coloured scanning electron micrograph (SEM) of the five anthers of the flower of an oleander plant (Nerium sp.). These form part of the male reproductive structures of the plant (stamens). The anthers,which are fused at their tips (top left),produce the plant's pollen (small grains at lower right). The male sex cells in the pollen grains fertilise the female sex cells (ovules,not seen) held in the ovary. Magnification unknown | |
