PPT-DEFINITION OF STELE & STELER EVOLUTION IN PTERIDOPHYTES (AND HIGHER PLANTS)

TDC 2 ND SEMESTER Definition of Stele and Stelar System According to the earlier botanists the vascular bundle is the fundamental unit in the vascular system of pteridophytes and higher plants Van . Spring . 2014. Outline. Review of land plant phylogeny. Characters of seed plants. Gymnosperm phylogeny & diversity. Cycads. Gingko. Conifers. Gnetophytes. Review of land plant phylogeny. Green plants (viridophytes). Last week we talked about. …. The universe had a beginning. God must be the creator of the universe. 3 views Christians can faithfully hold: Old-Earth Creationism, Young-Earth Creationism, Theistic Evolution. What do we use in order to determine evolutionary relationships?. Fossil Record. Anatomical Evidence. Molecular Evidence. Embryological Evidence. Evidence for Evolution. Fossil Record. Evidence for Evolution. as Branches of. the Tree of Life. Overview. Plants, fungi and animals are the three kingdoms of multicellular organisms. .. Land plants are known to have evolved from organisms similar to some living green algae. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution.
