Document Summary
Freom tree to seed: transport in plants, plant nutrition and soils, plant defense, plant life on the edge. Lecture 1-2 outline: basal tree of life, bryophytes- liverwort, mosses, hornworts, lycophytes, ferns, gymnosperm, angiosperm, lycophytes-vascular plants. How they conquered of dry land by vascular plants: Cuticle, upper epidermis, pallisade layer, spongy mesophyll, lower epidermis, cuticle. Lycophytes example: clubmosses (400 species), quillworts (150 species), Althought they have the word mosses, they are vascular plants. mosses in general are nonvascular plants. Spikemosses are special kinds of mosses because they are vascular plants. Vascular plants are plants that have phloem and xylem which are efficient methods to uptake nutrients and water: ferns. Whisk ferns(2 species) and allies horsetails (15 species), true ferns (12,000 species). Today true ferns take up 75% of speciesin tropics, Tiny aquatic azolla ferns are the world"s smallest ferns. Through burial pressure, heat time: how peat turns into anthracite coal: peat>lignite>sub-bituminous coal, bituminous coal, anthracite coal.
