Major groups of plants

• Nonvascular plants

• Seedless Vascular Plants

• Gymnosperms

• Angiosperms

Page 6: Nonvascular and Seedless Vascular Plantsfacultyweb.wcjc.edu/users/kevind/Lab_Nonvascular_and...Seedless Vascular Plants •Contain vascular tissues –Xylem and phloem –True plant

Nonvascular plants

• Phylum Bryophyta

– True mosses

– Small

– No vascular tissue

– Live in moist habitats; why?

– Gametophyte generation dominates life cycle

Seedless Vascular Plants

• Contain vascular tissues

– Xylem and phloem

– True plant organs – root, stem, leaf

– Larger

– Role of water in life cycle

– Sporophyte dominates life cycle

Other Seedless vascular plants “fern allies”

• Phylum Monilophyta

– Horsetails

– Equisetum

• Strobilus

• Silica in hollow-stem; reduced leaves

• Phylum Lycophyta

– Lycopodium and Selaginella
