gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturity.

Strobilus or cone is the reproductive structure of gymnosperms. … Gymnosperm plants are heterosporous. They produce different spores, which are the haploid microspores and megaspores. Male Cones – the male strobili or male cones have microsporophylls, which have the microsporangia that produce the haploid microspores.
Which of the following is common to angiosperms and gymnosperms?

Is Cycas an angiosperm or gymnosperm?
Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements.
