This Concept Map, created with IHMC CmapTools, has information related to: Plant Diversity 1- Group 2, Fuel source Due to Peat Moss, Nonvascular Plants ???? do not have an extensive transport system, Gametophytes Produces Gametes, Bryophytes Gametophytes Dominant for nonvascular plants, Their chemical composition Matches Composition of plant spores today but differs from that of the spores of other organisms, Gave rise to vast diversity of living plants Distinguished through NONVASCULAR plants Phylum Anthocerophyta, Alternation of generations Step 2 2. The buds grow, Apical Meristems Sustains Growth of length throughout plant's life, Morphological and Molecular Evidence Evidence 1 Rings of cellulose- synthesizing proteins, Phylum Lycophyta Common name Lycophytes, Sori Definition Clusters of sporangia on the underside of sporophylls, Vascular tissue Create Vascular plants, Diversification of Plants Ancestral species Gave rise to vast diversity of living plants, 2 Clades Clade 1 Lycophytes, Gametophytes are tiny and grow below the soil surface ???? Bisexual, Ecological and economic importance Help Retain nitrogen in the soil, Derived Traits of Plants ???? Multicellular Gametangia, Gave rise to vast diversity of living plants Distinguished through NONVASCULAR plants Phylum Bryophyla, Peat Moss Definition A major component of the deposits of partially decayed organic material, Plant Diversity I Plant Group #2 Seedless Vasular Plants
