Vedclass · Answer

(D) The process starting from the landing of pollen grains on the stigma until the pollen tube enters the ovule is collectively known as $Pollen-Pistil$ interaction. This is a dynamic process involving pollen recognition followed by promotion or inhibition of the pollen tube growth. It is a dialogue between the pollen grain and the pistil mediated by chemical components of the pollen interacting with those of the pistil.
