Title: Kingdom


1
Kingdom Plantae ???
  • without flowers / fruits with flowers /
    fruits
  • (Non-flowering Plants) Phylum
    Angiospermophyta

  • ????

  • (angiosperms)
  • without seeds
    with seeds
  • Phylum
    Coniferophyta ????

  • (conifers/gymnosperms)

  • without with
  • vascular tissues vascular
    tissues (?????)
  • Phylum Bryophyta Phylum Filicinophyta
  • (mosses) ?
    (ferns) ?

2
Phylum Mosses e.g. Polytrichum
  • Habitat (???) damp / moist ( ??),
  • shady(??) and
    cool habitat.
  • Features
  • Less efficient water conservation / uptake
  • (???????)
  • 1. Gametophytes have no cuticle (???), water and
  • nutrients (??) diffuse (??) rapidly in and
    out.
  • 2. No true root / have only rhizoids, (????,?
  • ???), water uptake is less efficient (??????
  • ?)
  • 3. Gametophytes grow tightly in form of a mat for
  • water retention. (??????????????
  • ????)

Phylum Mosses e.g. Polytrichum
  • Water necessary for reproduction
  •  
  • Male gametes (???) are motile (???), a water
    medium is necessary for their movement to female
    gamete to carry out fertilization to complete the
    life cycle. (?????????????????)
  •  

5
Phylum Mosses e.g. Polytrichum
  • External features of mosses
  • 1. Gametophyte has leaves with chlorophyll to
  • absorb light for photosynthesis.
  • 2. Gametophyte has rhizoids (??) for water
    absorption.
  • 3. Sporophyte has a small amount of chlorophyll
    for photosynthesis and is partially dependent on
    gametophyte for food (??????????).
  • 4. Sporophyte has foot (??) to absorb food
    and water from the gametophyte.
  • 5. Sporophyte has capsule (??)which contains
    spores (??) for reproduction.

6
  • 6. The capsule of sporophyte is elevated by
    elongation of seta and the hygroscopic nature of
    peristome requires a dry atmosphere for
    liberation and dispersal of spores. It shows
    full adaptation to disperse the spores in dry
    conditions.

Ferns
8
Ferns (????)
  • a. Habitat open areas, hillside / roadside /
    walls
  • B. Features
  • For water conservation / uptake
  • 1. Frond (??) has hairy cuticle (??????).
  • 2. True roots (adventitious root ???) for water
    uptake and vascular tissues (????) to conduct
    (??) water ? stand drier areas (??????).
  • Water necessary for reproduction
  • 1. Male gametes (???) are motile (???), a water
    medium is necessary for their movement to female
    gamete to carry out fertilization to complete the
    life cycle. (?????????????????)

9
External features of ferns
  • 1. Fronds have chlorophyll
  • 2. Fronds have hairy cuticle
  • 3. True roots and vascular tissue
  • 4. Sorus / sori (????) on lower surface of frond.
  • 5. Annulus (??) and stomium (??)
  • of sporangia (???) favours spore
  • dispersal in dry atmosphere.

10
Gymnosperm (????)
  • Habitat Open dry areas, hillside
  • No flowers and fruits, with seeds
  • Green leaves
  • Leaves needle-shaped (??) /
  • scale- like (???)
  • Leaves with thick cuticle(????)
  • Cones (??) for reproduction.
  • Roots

Gymnosperm

Male cone

Female cone

Mature female cones seed
15
Xerophytic features of Pinus leaf (????????)
  • 1. Thick cuticle
  • 2. Transverse section (???) of leaf is
    semi-circular (???)
  • 3. Sunkened stomata (????) trap water vapour
  • Resin ??

Angiosperms / flowering plants) ????
  • 1. Flowers
  • 2. Fruits
  • 3. Roots
  • 4. Green leaves
  • 5. Leaves with cuticle
  • 6. Leaves with midrib (??)
  • Divided into two groups Monocotyledonous plant
    (?????) and dicotyledonous plants (?????)
  • Monocot are herbaceous plants (????) Dicot are
    herbaceous or woody (???)
