plant test

vascular and non vascular

vascular have vascular tissue non vascular don’t have vascular tissue

specialized tissues for the transport of water, nutrients and products of photosynthesis

algae, bryophytes (mosses,hornworts)

ferns, gymnosperms, angiosperms

chlorophyla, rhodophyla, phaeophyla

• always found in aquatic or moist environments • don’t have true leaves and stems called blades and stripes • life cycle follows alternation of generations

found in all plants where for part of the life cycle the plant is haploid and other part is diploid

the gametophyle produces two gametes which fusion together into a zygote the zygote goes into mitosis into a sporephyte the sporophyte goes into meiosis and produces spores

-red colour -mostly found in ocean environments most are multicellular stores food in form of starch

• green colour • unicellular, multicellular or colonial • found in freshwater • store food in starch form

• brown colour • store food in starches and oil form • found in marine environments temperate and artic areas

• has feathery/leafy frounds - gametophyte much smaller and separate from sporophyte in alternation of gen

• clumped habit - gametophyte and sporophyte is attached in alternation of gene

all bear cones, with naked seeds

conifers, cycads, ginkgoes, gnetophytes

• in cooler regions and in desert habitats • leaf curl to reduce water loss • cone bearing seed plant with needles like leaves

spruce trees, pine trees, junipers

seed plants have stout and woody trunks

-fan like leaves yellow flowers -Chinese plant

cones angiosperms like leaves

they have flowers and bear fruit

monocots and dicots

• single cotyledon • flower parts in multiples of 3 • leaves with parallel lines • die off each year • vascular bundles scattered randomly in stems
