No members of the family attain dominance over immense geographic range, but they can achieve considerable local and regional prominence - eg. The sporophytic plant body is by and large arborescent in gymnosperms while it is not so in pteridophytes. Molecular systematic evidence is suggesting these are closely related if not imbedded in conifers, rather than close to angiosperms as usually assumed.

Life as we know it would not exist without plants to convert sunlight and inorganic compounds into food energy. Gymnosperms are a smaller, more ancient group, and it consists of plants that produce "naked seeds" (seeds that are not protected by a fruit). Palm-like plants found mainly in tropical and subtropical regions. Male gametes are ciliate in pteridophytes, while they are not in gymnosperms (except for few like cycas).

Flowers and seeds are not produced. Water is no longer required for sperm to unite with egg; instead the partly developed male gametophyte (= pollen grain) is transferred to the vicinity of a female gametophyte within the ovule: this is known as pollination. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); BotanyZoologyBiochemistryCell & Molecular BiologyBiotechnologyBioinformaticsBiophysicsPlant PhysiologyPhysiology & EndocrinologyImmunologyMicrobiologyGeneticsEmbryologyEvolutionEcologyResearch MethodologyBiostatisticsPhysics for BiologistsChemistry for Biologists.
