Royal Ann flowers are hermaphroditic, containing both male and female reproductive organs, however, the tree cannot self-pollinate. Another pollinator species is necessary in order for fertilization to occur, most commonly bees. [3] Each flower goes on to produce a single Royal Ann cherry.
The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees ...
The anther produces pollen grains that contain male gametophytes. The pollen grains attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules) are located. Plants may either self-pollinate or cross-pollinate. The transfer of pollen (the male gametophytes) to the female stigmas occurs is called pollination.
Urban planting of male Ginkgo biloba in Riverside, Illinois. Botanical sexism is a term that describes the preferential planting of cloned male plants in urban areas because they do not produce fruits and flowers that litter the landscape. However, because males produce pollen, areas with only male plants can have high pollen in the air and ...

Floral sexuality is related to the presence or absence of the reproductive whorls: androecium and gynoecium. Flowers that have both whorls (i.e., will produce both male and female gametes) are said to be perfect, bisexual, monoclinous or, more frequently, hermaphrodites, as is the case with potato flowers (Solanum tuberosum, Solanaceae
