Autogamy and geitonogamy

Vedclass · Answer

(B) In flowering plants,$Autogamy$ refers to the transfer of pollen grains from the anther to the stigma of the same flower.$Geitonogamy$ refers to the transfer of pollen grains from the anther to the stigma of another flower of the same plant.$Dioecy$ (the condition of being dioecious) is a mechanism where male and female flowers are borne on separate plants.Because the male and female flowers are on different plants,the plant cannot perform $Autogamy$ (as it requires the same flower) or $Geitonogamy$ (as it requires the same plant).Therefore,dioecy prevents both $Autogamy$ and $Geitonogamy$.
