1. Kingdom Plantae

2. Characteristics of Plants:
All plants are multicellular eukaryotes
All plants are made of tissues and organs.

3. Characteristics of Plants:
All plants have a cell wall.
Contain chlorophyll for photosynthesis
Autotrophs!

4. Living on Land
Plants must find ways to get water, support their bodies and reproduce!

5. Plant Parts: Leaves Leaves: capture sun’s energy for photosynthesis
Contain openings
called stomata that can
take in CO2 and stop
water loss

6. Plant Parts: Stems
Stems: carries substances from roots to leaves & provides support

7. Plant Parts: Roots
Roots: anchor plant and absorb water and minerals

8. Transporting Materials
Water taken in at roots
Food made in leaves
Vascular Tissue:
tubes inside the plant
that transport material
up and down!

9. Vascular Tissues Xylem: tissue that carries water up to plant
Phloem: tissue
that carries food
down to plant

10. Carnation Demo

11. Plant Response
Tropism: a plant’s growth response towards or away from a stimulus
EX: Phototropism: growth towards light

12. Video Review

13. Classification of Plants:
Nonvascular - no system of water transportation
Vascular - contain vascular tissues that transfer water & food

14. Nonvascular Plants: Transport materials through absorption
Low to the ground
Must live close to water

15. Examples
Mosses
Hornworts
Liverworts

16. Vascular Plants: Most plants are Vascular
Has a water transport System!
Have stems, roots, and leaves!

17. Seedless Plants Ferns, Horsetail, Club Moss
All use spores to reproduce

18. Seed Plants Use seeds to reproduce Have stems, leaves, and roots
Much more numerous!

19. Seed Dispersal Seeds protect the young plant
Scattered by wind, water, or animals
Germination: when the seed begins to grow

20. Gymnosperms VS. Angiosperms
Produce “naked” seed
No protective covering
Needle-like leaves and deep root system
Adapted to live in dry/cold places
Produce flowers & fruits
Seed protected by fruit or covering
Live almost everywhere

21. Gymnosperms Cycads, Gingkos, Gnetophtyes, & Conifers
Most reproduce using cones that contain pollen

22. Angiosperms Examples: Palm trees, fruit trees, flowering plants, etc.
Reproduce using pollen

23. Monocots VS. Dicots Monocots Dicots “di ” means two two cotyledons
“mono” means one
one cotyledon (seed leaf)
Leaves are long a thin in multiples of 3
“di ” means two
two cotyledons
Wide branching leaves in multiples of 4 or 5

24. Examples Monocots Dicots Corn Tulips Wheat Tomatoes Maple trees
Sunflowers
Roses
