Kingdom Plantae

Kingdom Plantae
Types
- Vascular
- Non- seeded
- Life cycle dominated by
Sporophytes
- Plant Structure
- Allowed plants to grow taller
and gain access to sunlight
- Independant Sporophytes
- Seeded
- Morphology
- Ovule
- Pollen
- Angiosperms
- Morphology
- Fruits are mature
ovaries
- Help disperse seeds of the
plant
- Reproduces with
the flower
- Seed plants that produce
flowers and fruits
- Groups
- Gymnosperm
- Non-Vascular
- Life cycle is dominated by
Gametophytes
- Sporophytes rely on the
gametophyte for survival
- Non vascular means they do
not have xylem or phylem
tissues
- Accounts for their small size
- Water is required for
fertilization
- commonly called bryophytes
- Examples of Organisms
- Liverworts
- Hornworts
- Mosses
- Closely related to vascular
plants
- Plant Structure
- Gametophytes
- Protonema
- Proto (first) nema (threads). A
one cell thick mass that
absorbs water and minerals
- Gametophore
- Rhizoids
- Structures that anchor a gametophyte to
the ground. Long tubular either single cell
or filaments of cells
- Sporophytes
Origins
- Green Algae (Charophytes)
- Reasons for colonizing
land
- Evidence
- Sporopollenin prevents
zygote from drying out
- 500 MYA
- Symbiotic relation between
fungi and first land plants
- fungi gave plants (without
roots) nutrients
General Information of all Plants
- Alteration of Generations
- Important Terminology
- Gametophyte
- A haploid plant that
produces gametes by
Mitosis
- Sporophyte
- Bryophyte
- Refers to all non vascular
plants
- Ovule
- Embreophytes
- Land plants
- Cuticle
- Gametangia
- Antheridia
- Male gametangia, where
many sperm are produced
- Where gametes are
produced
- Archegonia
- Female gametangia where a
single egg is produced
- Four traits of all land
plants
- Alternation of
Generation
- Apical meristems
- Localized regions of
cell division
- Walled Spores produced
in sporangia
- Multicellular
gametangia
Importance
- Ecological
- helps the colonization of
new land
- Seeded plants are the
dominant producers
- Economical
- Fuel
- Fossil Fuels
- Decay of Carboniferous
forests became coal
- Alternative Fuel
- mosses decay to peat
which can be burned
- Food
- Wood
- Medicine
- Secondary compounds
