WebJun 26, 2024 · One fertilizes the egg, and the other one helps make endosperm through a process known as double fertilization. Fertilized eggs mature into seeds protected inside fruit. Reproductive Processes of Gymnosperms Sporophytes in gymnosperms make male and female gametophytes.
WebPlants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte. WebGymnosperms (e.g. pines), non-seed organ plants (e.g. ferns), and non-organ plants (e.g. mosses) do not have this double fertilization. In many flowering plants, endosperm nutrients are transferred to the embryonic leaves of the developing plant called cotyledons.
