Spermatophytes (Gymnosperms):The most successful and advanced class of land plants are the spermatophytes (i.e., sperma-seed). One of the major troubles that had to be faced by plants living on land was the vulnerability of their gametophyte generation. For illustration in ferns the gametophyte is a delicate prothallus and it generates the male gametes (that is, sperms) that are dependent on water for swimming to reach the female gamete in the archegonia. In seed plants, though, the gametophyte generation is protected and much reduced. Three significant developments have been made by the seed plants. A. Development of heterospory.
B. Development of seeds.
C. Development of non-swimming male gametes.
