1 Classification of Plants

2 Plant Kingdom Non-flowering Plants Flowering Plants

3 Non - flowering Plants Do NOT produce flowers
. 3 groups Non - flowering Plants Mosses Ferns Gymnosperms Do NOT produce flowers

4 A plant can be divided into 3 parts

5 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 A leaf (finely divided into small parts)
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 Flowering Plants . 2 groups Monocotyledons Dicotyledons
. roots, stems, leaves . vascular tissues (transport) . flowers, fruits (contain seeds)

17 Monocotyledons Parallel veins

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

19 Dicotyledons Veins in network

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

21 Plant Classification Plants Non-flowering Flowering 1 seed-leaf
2 seed-leaves Spore-bearing Naked seeds Monocots Dicots Gymnosperms No roots with roots Mosses Ferns
