Kingdom Plantaeaka Plants!
2
Plants

• many shapes, sizes, internal structures
• 2 phyla for plants
• tracheophytes vascular tissue
  
• ( true roots, leaves
  and stems)
• Seedless
• Seeded
• bryophytes nonvascular plants
  
• ( no true roots,
  stems, leaves)
• Provide most living things with food O2
• Are Autotrophs
• Are Eukaryotes

3
Non Vascular Plants

• A.k.a- Bryophytes
• Low growing plants
• Lack vacular tissue
• Xylem- tubes transport water
• Phloem tubes transport
• foodGLUCOSE!

4
Characteristics

• Autotrophs
• Multi-cellular
• Asexual reproduction
• spores
• Sexual reproduction
• Sperm and egg cells
• Require water to reproduce
• Eukaryotic

5
Examples Include

• Mosses Liverworts Hornworts

6
Vascular Plants

• A.k.aTracheopytes
• Contain true roots, leaves and stems
• Have vascular bundles
• Can be seedless
• Can be seeded

7
Non seeded vascular plants

• Have vascular tissue
• Do not use seeds to reproduce
• Ex. Horsetails, Ferns

8
Seeded Plants

• Have vascular tissue
• Produce seeds (to reproduce)
• 1. Gymnosperms
• Cone bearing plants
• 2. Angiosperms
• Flower bearing plants

9
Characteristics of Seeded Plants

• Seeds made up of
• Embryo fertilized seed develop into the young
  plants
• Stored food
• Seed coat

10
Gymnosperms

• Produce naked seeds
• No fruit covering
• Needlelike/scale-like leaves
• Cones are reproductive structures
• Male and female cones
• Include cycads, ginkos, gnetophytes and conifers

Angiosperms

• Flowering plants
• Plants which produced seeds which are protected
  by fruit
• 2 categories
• Monocots
• Dicots

15
Monocots

• Having only one seed leaf or cotyledon
• Leaves have parallel veination
• Flower petals in 3s or multiple of 3s
• Scattered Vascular bundles within the stem (
  cross section)

16
Dicot

• Having 2 seed leaves or cotlyledons
• Netted veinetion
• Flowers in 4/5s or multiples of 4/5s
• Vascular bundles are arranged wihtin the stem
  (cross section)

REMEMBER!!!

• Cells are different from animal cells
• plants have cell wall and animal cells do not
• b. vacuole large in plants, small in animal cells
• c. plants have chloroplasts, animal cells do not
