Last Answer : Metaxenia is – Effect of pollen grains on structure of maternal tissue of seeds.
Description : The floral part that receives pollen grains during pollination is - (1 ovary (2) style (3) stigma (4) ovules
Last Answer : (3) stigma Explanation: The stigma is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. The stigma receives pollen at pollination and it is on the stigma that the pollen grain germinates. The style connects the stigma to the ovary.
