This Concept Map, created with IHMC CmapTools, has information related to: Plant Diversity 1- Group 3, Diversification of Plants Bryophytes Nonvascular, Seedless Vascular Plants 2 Clades lycophytes (the club mosses & their relatives), Nonvascular Three phyla hornworts (Phylum Anthocerophyta), Derived Traits of Plants Ferns and other seedless vascular plants were the first to grow tall, Seedless vascular plants now found in mostly damp environments Homosporous (single type of spore), Formation of a phragmoplast ???? A group of microtubules known as the phragmoplast forms between daughter nuclei of a dividing cell. A cell plate then develops in the middle of the phragmoplast. Only occurs in plants and charophytes, Seedless vascular plants have flagellated seeds that swim through film of water to reach eggs Developed life cycles w/ dominant sporophytes, Adaptations that Enabled Plants to Move onto Land third Stomata: exchange gases, small parts in the leaves. can open and close depends on wheather conditions., Morphological and Molecular Evidence Evidence 4 Nuclear, chloroplast and mitochondrial DNA similarities, Morphological and Molecular Evidence Evidence 2 Structure of flagellated sperm, Nonvascular Three phyla mosses (phylum Bryophyta), Nonvascular Plants ???? represented by 3 phyla of small, herbaceous plants, Evolution of Plants from Green Algae Plants would diversity into 4 major groups Diversification of Plants, represented by 3 phyla of small, herbaceous plants ???? liverworts, Nonvascular Three phyla liverworts (Phylum Hepatophyte), Structure of flagellated sperm ???? Plants have flagellated sperm that closely resembles that of charophyte sperm., liverworts ???? Diverged from plants lineages from early plants evolution, Diversification of Plants flowers Angiosperms (90% of living plant species), Rings of cellulose- synthesizing proteins ???? Distinctive circular rings of proteins embedded in plasma membrane., Adaptations that Enabled Plants to Move onto Land ???? Gametophytes: is a haploid and produces haploid gamates by Mitosis
