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. A diploid megaspore mother cell is produced within the megasporangium, which will divide by meiosis to produce the haploid megagametophyte (see Chapter 7.3.2: Angiosperm Life Cycle for a refresher).
