9. Size of
bryophytes
is limited
as they do not have
vascular issue
(phloem and xylem)
40 cm
the tallest species is
about 40 cm high
10. Bryophytes have:
very simple structure (thallus), having no
proper roots, leaves or stems
hair-like structures
(rhizoids) on the
lower surface to
absorb moisture
Thallus
Rhizoids
11. Bryophytes are found in damp &
shady places
Waxy cuticle is absent or if present, is
inefficient
12. Bryophytes are mainly found in
damp places
as male sex cells need water to swim in
18. Ferns can attain
considerable
sizes (20 m):
as they have
vascular tissue
i.e. ferns have:
support
long-distance
transport
19. Ferns can live in drier environments
than mosses because:
a waxy layer waterproofs the plant’s
surfaces to reduce water loss
Note shiny
surface due to
a waxy layer.
20. Ferns can live in drier environments
than mosses BUT:
grow best in damp, shady places
22. Ferns reproduce also sexually
Ferns need water for reproduction like
mosses
Male sex cell of a fern. Flagella help it to
swim towards the female sex organ.
23. Question: SEP, 2011
Give a biological explanation for each of the
following statements.
Ferns are much better adapted to life on land
than algae. (5)
24. Algae are not adapted to live on land for two
main reasons.
Algae have no protection against drying up and
lack supporting tissue.
Ferns have an efficient waxy cuticle and
vascular tissue to help in support and long-
distance transport of materials.
Algae in aquarium.

down water loss.
33. Characteristic Bryophytes Ferns
Live only in damp shady places.
Do not have proper roots but have
rhizoids.
Have a proper vascular system.
Can reproduce by means of spores.
Can grow to considerable sizes.
Liverworts are a member of this
group. [Not in syllabus]
The leaves have a waxy layer to cut

34. Question: MAY, 2010
1. Explain why bryophytes tend to be small
plants while ferns are larger plants. (2)
Bryophytes are small as they lack vascular
tissue. This means that they cannot
transport materials over long distances.
Bryophytes cannot support themselves due
to lack of xylem.
Better anchorage in ferns by roots rather
than rhizoids in bryophytes.
35. Question: MAY, 2010
2. Ferns colonise drier areas than bryophytes.
Explain. (2)
As ferns have an efficient waxy cuticle. The
waxy cuticle is either absent or inefficient in
bryophytes.
