Seedless Vascular Plants No seeds yet Vascular tissue o 3 tissue systems dermal tissue system epidermis of the plant runs continuously covering outer surfaces of all plant parts ground tissue system filler between dermal and vascular tissue makes up the bulk of plant parts photosynthesis occurs here and storage of photosynthetic materials vascular tissue system found within veins in leaves specialized for water transport runs continuously through all plant organs more than one type o xylem o phloem – transport water with sugars and starches dissolved in them down stem to the roots Plant organs o Roots – under ground o Shoot – above ground parts of the plant Stems and leaves (or modified version) Microphylls – tiny, simple leaves o first ones ever evolved by plants o single vein of vascular tissue Megaphylls – big leaf o Branching venation Annuals – single year life cycle Perennials – live from year to year o Primary growth – increase in length; shoots get taller and roots get longer o Secondary growth – increase in girth Homospory – just one kind of spore Heterospory – more than one kind of spore is produced o Microspores – male Grow up to be microgametophytes which produce microgametangia with microgametes (sperm) Microgametophytes = pollen o Megaspores – female Megagametophytes; stay in the sporangia on the sporophyte Megagametophytes produce ovules that will be fertilized through pollination Ovules grow up to be seeds Dominant sporophyte generation 4 major groups today o 2 phyla Monilophyta (biggest group) Pterophytes – true fern (biggest group of plants outside of the flowering plants) Psilophytes – whisk “ferns” Arthrophytes – Equisetophytes (horsetails, grasses, scouring rushes) o Nodes – where leaves are attached o Internodes – area in between nodes o Microphylls o Whorl – more than two leaves attached to a single node o Opposite – one leaf on either side o Alternate – only one leaf at a time p. Lycophyta – club “mosses” Fern life cycle Dichotomous – two way branching o Branching of psilophyte stem
