a label the phylogenetic tree of the 4 major lineages of land plants inferred from dna sequence

Step 1: Identify the four major lineages of land plants discussed in the question: Bryophyta, Pt

Question

A. Label the phylogenetic tree of the four major lineages of land plants inferred from DNA sequence data and discussed in class. Label the following groups of plants: Bryophyta, Pteridophyta, Anthophyta, Psilotophyta, Hepatophyta, Lycophyta (include both Lycopodium and Selaginella), Coniferophyta, Sphenophyta, and Chlorophyta. B. Please show on the correct branches where each of the following characteristics is thought to have evolved. Some of these characteristics are likely to have evolved multiple times and therefore may appear on more than one branch. 1. Free-living sporophyte 2. Terrestrial lifestyle 3. Pollen tubes 4. True leaves 5. Seeds 6. Vascular tissue
