Chara: A modern algae that resembles primitive plant ancesters.
Seedless non vascular plants • Seedless Non Vascular plant Characteristics: • No flowers, has separate archeogonium (xxxx) and antheridium (xxxx) • Produce spores • Does not produce pollen, has flagelated sperm. • Not associated with the insects. • Gametophyte (dominant generation) and sporophyte generation independently living but sporophyte growing out of gametophyte. • No vascular system; nutrients moved through difusion.
The Seedless Vascular Plants. • Seedless Vascular plant Characteristics: • No flowers, has separate archeogonium (xxxx) and antheridium (xxxx) • Produce spores • Does not produce pollen, has flagelated sperm. • Not associated with the insects. • Gametophyte (generally dominant) and sporophyte generation independently living. • Vascular system: Xylem: Tracheids and Phloem: sieve tube members
Salvinea: A noxious introduced aquatic fern from the new world.
Gymnosperms: The first seed plants. • Gymnosperm Characteristics: • No flowers • Produce seeds that are not contained within an ovary • Produce pollen • Not closely associated with the insects. • Dominant speorophyte generation • Vascular system: Xylem: Tracheidsand Phloem: sieve tube members
Bowinea: The byfield fern, a rare native fern found in central Queensland.
Angiosperms: The Modern Insect Symbionts. • Angiosperm Caharestics: • Produce flowers • Produce seeds that are contained within ovaries • Produce pollen • Close association with the insects • Dominant sporophyte generation • Vascular system:Xylem: vessel elementsand Phloem: sieve tube members
Dicotyledons: The flowering plants with two cotyledons. • Docotyledon characteristics: • Two cotyledons • Leaves petolate • Netted venation • Flower parts in serts of 4 or 5. • Secondary growth • Tap roots
Monocotyledons: The Flowering Plants with one cotyledon. • Monocotyledon Charasteristics: • Only one cotyledon • Leaves thatg are stem clasping • Parrell venation • Flower parts in sets of 3 • No secondary growth • No tap roots
