Pistil of a flower. Coloured scanning electron micrograph (SEM) of part of the pistil of a cinquefoil flower (Potentilla sp.). The pistil is the female reproductive part of a flower,comprising one or more carpels. Each carpel is made up of a stigma (tip,dark orange) borne on a style (shaft,light orange). Pollen,the male sex cells of a flowering plant,lands on the stigma and burrows down through the style to reach the ovary at the style's base. It then fertilises the ovum there,forming a seed | |
