Gladiolus flower anther. Coloured scanning electron micrograph (SEM) of a gladiolus flower (Gladiolus sp.) anther. Anthers are part of a plant's male reproductive system. They produce the male gametes (sex cells),pollen grains. The ribbed structure seen here splits open to release the pollen. The pollen grains fertilise ovaries,the female gametes.
