Document Summary

I. outcomes: compare basic plant characteristics to the other eukaryotic kingdoms (and the protists), list the basic feature of plants, ancestral and derived, trace and diagram the life-cycle of a moss and a fern. Now, can you compare to a fungus, too: timeline of the evolution of plants, from algal ancestors through vascular plants. A. domain: plants are in eukarya, they are part of the archeplastida, a monophyletic clade. B. evolved from the ancestral charophytes: modern charophytes -> sister taxon to land plants. D. shared ancestral traits of land plants and charophytes: rings of cellulose-synthesizing proteins- make microfibrils of cell walls, structure of flagellated sperm- similar in both, phragmoplast- groups of microtubules (cell plate) between daughter nuclei, scaffold for cell plate assembly. E. seven derived traits of land plants (important: figure 29. 3: 1. ) Multicellular: dependent embryos, 2n embryo retained within tissue of female gametophyte, nutrients transferred parent -> embryo through transfer cells, land plants also known as embryophytes. , 3. )
