Nonvascular plants Flashcards
Bryophytes
- the earliest lineages to diverge from the common ancestor of land plants
- paraphyletic group that diverged before the evolution of vascular tissue
Bryophytes consist of three phyla of non-vascular plants
liverworts, mosses, and hornworts
Phylum for liverworts
hepatophyta
Phylum for mosses
Bryophyta
Bryophyta refers to one phylum _____ but bryophyte refers to:
mosses versus all nonvascular plants
Phyla for hornworts
Anthocerophyta
Bryophytes lack
true vascular tissue and lignin
Bryophytes tissues are _____ thick
few cells
Bryophytes absorb water by:
through their surfaces (they don’t have roots)
Only ____ and ____ have stomata for gas exchange
mosses and hornworts
• Bryophyte sporophytes are
unbranched, and lack roots and leaves
for bryophytes, gametophytes are ____ than sporophytes
larger and longer-living
Bryophytes are common and diverse in
moist forests and wetlands
Mosses have an important role in regulating water flow because
Mosses can lose most cellular water, and
then rehydrate and reactivate cells when
moisture becomes available
