There is continuous interaction between pollen grain and pistil which is mediated by the chemical components of pollen.
Two steps : Pollen grain germinates on the stigma to produce pollen tube and the contents of the generative cell move into the pollen tube. Pollen tube grows through the tissue of stigma and style by secreting enzyme.
