Strawberry plants are sedentary; therefore, they rely on other organisms to carry their seeds. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation. Anemochory can be eliminated as strawberry seeds are imbedded in relatively heavy fruit, have no dispersal structures and their seeds are too large to be carried by wind.
