3.  3 groups
FernsFernsMossesMosses GymnospermsGymnosperms
Non - flowering Plants
Do NOT produce flowers

4. A plant can be divided into 3 partsA plant can be divided into 3 parts

5. Examples of MossesExamples of Mosses

6. spores
Spore-producing capsule

7. No true roots, No vascular tissues (no transport)
Characteristics of MossesCharacteristics of Mosses
Simple stems & leaves
Have rhizoids for anchorage
Spores from capsules (wind-dispersal)
Damp terrestrial land
Simplest plants

9. underground
stem
root
A leaf (finely
divided into
small parts)

11. roots, feathery leaves & underground stems
Characteristics of Ferns
have vascular tissuesvascular tissues (transport & support)
DampDamp & shadyshady places
Spore-producing organSpore-producing organ on the underside of
leaves (reproduction)

13. needle-shaped leaves

14. Male cones
(in clusters)
Female cones
(scattered)

15. roots, woody stems
Characteristics of GymnospermsCharacteristics of Gymnosperms
needle-shaped leaves
tall evergreen trees
cones with reproductive
structures
dry places
vascular tissues (transport)
naked seeds in female cones

Plants
roots, stems, leaves
vascular tissues (transport)
flowers, fruits (contain seeds)

17. MonocotyledonsMonocotyledons
Parallel veins

18. one seed-leaf
Characteristics of MonocotyledonsCharacteristics of Monocotyledons
 leaves have parallel veins
herbaceous plants
e.g. grass, maize

19. DicotyledonsDicotyledons
Veins in network

20. two seed-leaves
Characteristics of DicotyledonsCharacteristics of Dicotyledons
leaves have veins in network
e.g. trees, sunflower, rose
