In terms of number of species, not a large group of plants. They are classified into two parts: Gymnosperms and Angiosperms. Seeds seem to be one of the factors responsible for the dominance of seed plants in today's flora. Please refer to the appropriate style manual or other sources if you have any questions. In the two great groups of seed plants, gymnosperms and angiosperms, the sporophyte is the dominant phase in the life cycle, as it is also in the vascular cryptogams; the gametophytes are microscopic parasites on the sporophytes. 2. evident reproductive organs called flowers.

Unlike angiosperms (= "encased seeds"), gymnosperms are all grouped together because the seeds are "unprotected" or naked, that is exposed on the surface of bracts. Pteridophytes occupy the intermediate position between Bryophytes and Gymnosperms (seed plants). The species is dioecious: the ovulate trees produce an abundance of trees which have a particularly obnoxious odor. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers. This cookie is set by GDPR Cookie Consent plugin. Suspensor is formed during the embryo development in both groups. The Phanerogams are classified into two parts such as: Gymnosperms are naked seeded plants. Fertilized eggs mature into seeds protected inside fruit. Gymnosperms are naked-seeded plants. Many have beautiful petals, fragrant blossoms and fruit that contains dozens of seeds. Gnetopsida-eg: Gnetum Gymnosperms vs Angiosperms b) Angiospemae Angiosperms (Gk.angion=hidden; sperma=seed) are flowering and seed bearing plants. developing under ground Suspensor formation is present in some Pteridophytes and all Gymnosperms. represent the non-seed bearing plants.
