Vedclass · Answer

(c) : Unisexuality or dicliny is a condition in which two types of unisexual flowers are present $i.e.$, staminate (male flower) and pistillate (female flower). The plant may be monoecious or dioecious. This is a device for cross pollination (or xenogamy). Both xenogamy and geitonogamy ($i.e. $ transfer of pollen from anther of one flower to stigma of another flower of either the same or genetically similar plant) are included under allogamy/cross pollination. Autogamy or self pollination ($i.e.$ transfer of pollen from anther to stigma of the same flower) occurs in bisexual flower.
