(D) The pollen-pistil interaction is a dynamic process involving pollen recognition followed by promotion or inhibition of the pollen. This recognition is mediated by chemical components of the pollen interacting with those of the pistil. Specifically,the pistil has the ability to recognize the pollen,whether it is of the right type (compatible) or of the wrong type (incompatible). This recognition is achieved through a continuous chemical dialogue between the pollen grain and the stigma,which involves the interaction of specific proteins present on the surface of the pollen and the stigma.

The compatibility and incompatibility of the pollen-pistil interaction is determined by
