In early classification schemes, the gymnosperms (Gymnospermae) were regarded as a "natural" group. There is conflicting evidence on the question of whether the living gymnosperms form aclade.[1][2]The fossil record of gymnosperms includes many distinctive taxa that do not belong to the four modern groups, including seed-bearing trees that have a somewhat fern-like vegetative morphology (the so-called seed ferns or pteridosperms.)[3]When fossil gymnosperms such asBennettitales, Caytonia and the glossopterids are considered, it is clear that angiosperms are nested within a larger gymnosperm clade, although which group of gymnosperms are their closest relatives remains unclear. For the most recent classification on extant gymnosperms see Christenhusz et al. (2011)[4]
Classification:'
SUBCLASS CYCADIDAE
SUBCLASS GINKGOIDAE
SUBCLASS GNETIDAE
SUBCLASS PINIDAE
Gifford and Foster classified gymnosperms into four divisions: Cycadophyta (cycads), Ginkgophyta (ginkgo), Pinophyta (conifers), and Gnetophyta (gnetophytes). Each division is characterized by distinct features such as leaf structure, reproductive organs, and overall morphology. This classification system provides a framework for understanding the diversity and relationships among gymnosperms.
The scientific name for gymnosperms is Gymnospermae.
The seed-bearing cone belongs to gymnosperms, a group of plants that includes conifers, cycads, and ginkgo. Gymnosperms bear seeds on the surface of scales or leaves, rather than within a fruit.
No. Conifers are Gymnosperms.
gymnosperm (apex)
Gymnosperms have woody stems, which are typically covered in a thick layer of protective bark. The stems of gymnosperms also often contain vascular tissues for water and nutrient transport.
Neither. The monocot/dicot classification only applies to flowering plants.
