Non- Vascular Plants

1. Bryophytes

2. Major Characteristics:
 Bryophytes do not have true vascular tissues
for support and transport of water and nutrients.
 They lack leaves.
 However, they have leaf-like scales that
contains chloroplasts in which photosynthesis
occurs.

3.  They lack true roots
 They anchor themselves in the soil by root-like
structures called rhizoids.

4.  Lack of true stems
 Usually small and
ground-hugging. Most
measure between 2 to 4
inches.

5. Classifications

6. There are 3 classes of bryophytes:
1. Class Musci (Mosses)
2. Class Hepaticae (Liverworts)
3. Class Anthocerotae (Hornworts)

7. 1. Class Musci (Mosses)
 The body of the moss is usually leafy-like
 Most prefer damp, shaded locations in the
temperate zone.

9.  Mosses may also
asexually reproduce by
budding

10. 2. Class Hepaticae (Liverworts)
 The name liverwort arose because the
lobes of the thallus resemble the lobes of
the liver

11. Lobe of liver
Conocephalum
conicum
(Great Scented
Liverwort)

12.  Many have a flattened body called
thallus, but some have a leafy
appearance
 Some liverworts are capable
of asexual reproduction; in bryophytes
in general "it would almost be true to
say that vegetative reproduction is the
rule and not the exception.“ For
example in Riccia, when the older parts
of the forked thalli die, the younger tips
become separate individuals.

14. 3. Class Anthocerotae (Hornworts)
 The sporophytes of hornworts look like small
green broom hancles. Its shape os unique
among bryophytes.

15.  Unlike bryophytes and higher
plants most species of hornworts
have cells that contain only single
chloroplast
