THE ANCESTRY AND FEATURES OF LAND PLANTS
LAND PLANTS
(Bryophytes)
Non-vascular plant
Prefer moist locations
Low-lying
Dependent sporophyte produce windblown spores
Unbranched
Eg: liverworts, hornworts, mosses
Dominant gametophyte produce flagellated sperm
VASCULAR PLANTS
(LYCOPHYTE, FERNS AND ALLIES, SEED PLANTS)
Lycophytes
(club mosses)
Independent gametophyte produces falegellated sperms
Leaves are microphylls
Windblown spores produce in sporangia borne
Unbranched veins
Ferns and allies
(pteridophytes)
Branched veins
Dominant sporophytes produce windblown spores
Leaves are megaphylls
Independent gametophyte produces flagellated sperms
SEED PLANTS
(gymnosperms, angiosperms)
Gymnosperms
(cycads, ginkgoes, conifers, gnetophytes)
Cone-bearing
Existing in trees in forest
Usually large
Sporophytes bears pollen cones which produce windblown spores
Seed cones produce seeds
Angiosperms
( flowering plants)
Lives on all habitats
Following double fertilization
Diverse
Fruit develops from ovary
Ovules become seeds that enclosed a sporophyte embryo
