Detailed explanation-1: -Geitonogamy is the type of self-pollination where the transfer of pollen grains from the anther to the stigma takes place between different flowers in the same plant. Though it seems like cross-pollination and takes place with the help of pollinators, both the gametes have the same plant as their origin.
Detailed explanation-2: -Final answer: Pollination between flowers borne on two different plants of the same species refers to xenogamy.
Detailed explanation-3: -A flower is self-pollinated (a “selfer”) if pollen is transferred to it from any flower of the same plant and cross-pollinated (an “outcrosser” or “outbreeder”) if the pollen comes from a flower on a different plant.
Detailed explanation-4: -Only after pollination, when pollen has landed on the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds. A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary.
