Daisy flower and pollen. Coloured scanning electron micrograph (SEM) of pollen grains (round) on a pistil of a daisy (family Asteraceae) flower. Pollen grains are reproductive structures produced by the male parts of flowering plants. A pistil is one discrete unit of the female structures (carpel) of the flower. As each daisy flower actually consists of multiple tiny flowers,each one has it's own pistil | |
