Question

Below is a phylogenetic tree of a few major groups of photosynthetic organisms. At each node on the tree (branching point) we can list specific features, indicated by numbers, that are characteristic of the organisms higher on the tree. Using only the features provided in the list below, denoted by letters, place each feature in its appropriate spot on the tree. Each feature should be used only once. - Chlorophytes - Charophytes - Bryophytes - Club Mosses - Horsetails Terrestrial Ferns Ferns - Conifers Flowering Plants LUL T -10 +11 A-all plants heterosporous B-chlorophylls a &b C-circinate vernation D-cones with exposed ovules E-cuticle F-double fertilization G - embryo H-endosperm I-gametophyte generation dominant J-glycolate oxidase K-phragmoplast L-pollen M-seeds N-silica in cell wall 0-sporangia in sori P - sporic meiosis Q-stamens & carpels R-starch S-true xylem & phloem T-wood
