       Flowers have male and female
       parts. To make a seed, pollen
       passes from the male part of
       one flower to the female                                                             Anthers

          Insects
          Insects help to move pollen from the anther
          of one flower to the stigma of another. The pollen
          travels on their bodies. Once transferred, the
          pollen fertilizes the ovary to form seeds.          Flower shapes
