Evolution of Seed Habit: Pteridophytes vs Gymnosperms Labelled parts: Strobilus, Microsporangium, Megasporangium, Sporophylls, Heterospory, Male Cone, Female Cone, Ovuliferous Scale, Winged Seed. The production of two distinct types of spores (microspores and megaspores) by a plant, a precursor to the seed habit. A cone-like structure formed by the aggregation of sporophylls bearing sporangia. A plant structure in which megaspores are formed, such as the ovule in seed plants. The scale in a female conifer cone that bears the ovules.
