*Ground Tissue: the bulk of the plant body Parenchyma- controls photosynthesis and stores food Collenchyma- gives support to young and growing parts of the plant Sclerenchyma- gives support to older parts of the plant *Vascular Tissue: conducts water and nutrients throughout the plant Tracheids: hollow cells with thick cell walls that are connected end to end Xylem: transports water upwards from the roots Phloem: transports organic material (produced by photosynthesis) downwards from the leaves *Bryophytes: Mosses: can tolerate low temperatures and survive in harsh environments Liverworts Hornworts *Gametophytes are the dominant plant in bryophytes and sporophytes depend on the gametophyte for food.*Relatives of ferns: Club mosses: small plants that live in moist woodlands Horsetails Ferns: have rhizomes and fronds Rhizomes: underground stems Fronds: fern leaves *Roots- absorbs the water for the plant*Leaves- main photosynthetic system for plant*Stems- support system for the plantContains the Xylem and Phloem
