Title: Nonvascular Plants
1Non-vascular Plants
- Non vascular plants are called Bryophytes
- Bryophytes include
- Division Bryophyta (mosses)
- Division Hepatophyta (liverworts)
- Division Anthocerophyta (hornworts)
2A leafy liverwort Marchantia
3Gemmae cups of Marchantia allow asexual
reproduction
4Cross section of a gemmae cup. Fragments are
visible at cup bottom
5An antheridiophore containing antheridia (sperm
producers)
6This shows an archegoniophore of Marchantia Under
the umbrella are individual archegonia which
produce eggs. Eggs will be fertilized by sperm
from antheridia
7Close-up of archegonium. You can see an egg at
the top of this structure, and the neck canal
8Air pore in thallus of Marchantia
9Woodland moss, a Bryophyte
10Gametophyte with sporophyte growing off the top.
The sporophyte produces a sporangium, which
makes spores. The spores germinate into
protonemata which grow into mature gametophytes
11Moss sporangium. The calyptra has been removed
and the operculum is visible. Haploid spores are
maturing inside this structure and will produce
new protonemata
