Examples of Mosses
6
Spore-producing capsule
Moss
spores
7
Characteristics of Mosses
.Simplest plants
.No true roots, No vascular tissues (no
transport)
.Simple stems leaves
.Have rhizoids for anchorage
.Spores from capsules (wind-dispersal)
.Damp terrestrial land
8
Fern
9
Fern
A leaf (finely divided into small parts)
underground stem
root
10
spore-producing organs
(circinate) young leaf
11
Characteristics of Ferns
.roots, feathery leaves underground stems
.have vascular tissues (transport support)
.Spore-producing organ on the underside of
leaves (reproduction)
.Damp shady places
12
Gymnosperms
Pine tree
13
needle-shaped leaves
14
Male cones (in clusters)
Female cones (scattered)
15
Characteristics of Gymnosperms
.tall evergreen trees
.roots, woody stems
.needle-shaped leaves
.vascular tissues (transport)
.cones with reproductive structures
.naked seeds in female cones
.dry places
16
. 2 groups
Monocotyledons
Dicotyledons
. roots, stems, leaves
. vascular tissues (transport)
. flowers, fruits (contain seeds)
17

• leaves have parallel veins

. herbaceous plants
. e.g. grass, maize
19

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