Pistil has the ability to recognise the pollen grain of the right type.How? |
|
Answer» Mediation of continuous dialogue between pollen grains and the pistil by the chemical components of the pollen and pistil interaction helps in recognition of right or wrong pollen grain. If the pollen is of wrong type, the pistil rejects the pollen by preventing pollen germination on stigma or pollen tube growth in the style. |
