Most are terestrial
what is the domient stage of the non vascular plant life
haploid gemetophyta is dominent .
independent and photosynthetic .
what is the egg cell and the sperm cell named in bryophytes
egg cell - archegonia

Pterophyta - Nephrolepis
explain the features of lycophyta using seleginalla and lycopodium
seleginalla
- ground hugging
-spike moss

what gives evidence for the plant evolution during the Devonian and carboniferous periods
seedless vascular plants
what are the 5 major characteristics of seed plants ?
1.seed production
2.reduced gemetophyte
3.prodction of ovules and aggs
4.prodctuion of sperm and pollon grains
5.heterospory
what polymer makes the pollon wall hard ?
sporopollenin
what are the 4 major characteristics of seedless plants ?
1.xylem and phloem transpotation
2.root devolopment
3.leaves devoloped
4.sporopylls and spores
how does the fibers and trachids help seedless plants
the fibers and trachieds are made by lignin polymer and helps to grow tall trees helping absorb light and disperse spores.
