Pteridology, Gymnosperms and Palaeobotany (Bscbo-103) In Kingdom Plantae, plant species are classified according to their method of reproduction. Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Cycadofilicales (fossil) were considered as ferns for a long time and are still called as seed-ferns. In heterosporous Pteridophytes and in all Gymnosperms, the gametophyte development is endosporic (inside the spore wall). By contrast, gymnosperms such as pine trees produce bare, uncovered seeds, usually in pine cones. Continue with Recommended Cookies.
