Many seeds, as those of Aegle marmelos, Plumbago, mistletoe, etc., are sticky and are thereby benefited. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation. Most strawberry varieties are adept at multiplication in this fashion, and they are even considered an invasive weed in some situations. In this way, these seeds are dispersed through animal excreta often many miles from the place of their origin and often to very inaccessible places like tree tops and building cornices.
