1. Overview: Non-Vascular Plants
Phylum Bryophyta
Phylum Hepatophyta
Phylum Anthocerophyta

2. Phylum Bryophyta = the Mosses

3. Phylum Bryophyta = the Mosses
General characteristics:
short plants
no vascular system
no “true” stems, roots,
or leaves
need constant water
supply
for survival

4. Phylum Bryophyta = the Mosses
Habitat
wetlands, moist areas, areas with standing water
Depend upon
diffusion for
transport of
nutrients
Require
water for
reproduction

5. Phylum Bryophyta = the Mosses
Reproduction
Needs standing water for sperm to swim to eggs
Alternation of generations: alternation between a gameophyte generation & a sporophyte generation
Reproductive
structures =
SPORES
(no seeds)
Moss sperm
Moss spores

6. Phylum Bryophyta = the Mosses
Structures:
Capsule
/ Sporangium
Sporophyte
Gametophyte
Rhizoids (root-like)

7. Phylum Bryophyta : examples
Sphagnum
Function= retain water,
improve soil
e.g. aid in orchid cultivation

8. Phylum Bryophyta : examples
Plume moss

9. Phylum Bryophyta : examples
Common peat moss
Used to improve
soil water retention
Peat moss is a dead form of Sphagnum moss that grows in the North American taiga.

10. Phylum Bryophyta = the Mosses
Dominant generation of mosses =
gametophyte
this is the
sporophyte

11. Phylum Hepatophyta (Liverworts)

12. Phylum Hepatophyta (Liverworts)
short, flat plant
no vascular system
no “true” stems, roots, or
leaves
no stomata
habitat= wetlands
need standing water for
sexual reproduction
(sperm swim to eggs)
Dominant generation =
gametophyte

13. Phylum Hepatophyta – examples
Marchantia

14. Phylum Hepatophyta – examples
Monoclea forsteri

15. Phylum Hepatophyta – examples
Assorted liverworts

16. Mosses vs. Liverworts

17. Phylum Anthocerophyta Hornworts

18. Phylum Anthocerophyta Hornworts
short, flat plant
no vascular system,
no “true” stems, roots, or leaves
sporophytes have stomata
Habitat – wetlands
Reproduction - standing water for sexual repro. (sperm swim to eggs)
Dominant generation=
gametophyte
