Complete this phylogenetic tree to demonstrate the evolutionary history of the major plant groups and highlight some important adaptations. 1. Assign a major plant group [bryophyte; seedless vascular plant; gymnosperm; angiosperm] to the tips of the tree and 2. indicate where each of the following adaptations appeared (where you see a bar in a branch) [flowers; cuticle; seeds; fruits; stomata (or simple pores with no guard cells); vascular tissue; pollen]. Green Algae Chloroplasts with chlorophyll A and B Cellulose in cell wall Starch for energy storage Seedless, Vascular Evolution of vascular tissue Evolution of the seed Bryophytes Evolution of stomata Angiosperms Evolution of the waxy cuticle Evolution of the flower Evolution of pollen Gymnosperms Evolution of the fruit

Describe the evolutionary history of the four major groups of land plants. (bryophytes, seedless vascular plants, gymnosperms, and angiosperms.) - describe the adaptations that arose in each of the four major groups of land plants that helped facilitate their success. - describe why certain groups of land plants are less dependent on water for reproduction that other groups of plants

Review the phylogenetic tree shown. One of the major events in the evolution of plants was the encapsulation of the sporophyte embryo with a significant supply of stored nutritional sources within protective cell layers. Which letter on this phylogenetic tree indicates this evolutionary step? Other green algae Most closely related green algae Liverworts Mosses Hornworts Lycophytes Ferns and horsetails Gymnosperms Angiosperms Spores Xylem and phloem Alternation of generations Flowers Seeds and pollen
