Coloured scanning electron microscopy of a cacoa flower (Theobroma cacao). These small flowers grow directly from the trunk. The five erect structures are filaments, part of the male reproductive structure. They surround the carpel, the female reproductive structure that consists of the ovary (round) and stigma and style (erect from ovary). The pollen (male sex cell) bearing anthers are concealed in petal pouches (outside).
