THE PLANT KINGDOM

1
THE PLANT KINGDOM
2
All plants

• Are Multicellular
• Are Autotrophic photosynthetic
• Have cell walls with cellulose (that
  polysaccharide that we cant digest burp!)
• Have chloroplasts in their cells.

3
Basic plant Parts

• Leaves
• Stems
• Roots
• Flowers
• seeds

4
Leaves

• Main site of photosynthesis
• Consist of
• Blade
• Veins
• Petiole

5
Leaves can be simple or compound

• Simple have one blade
• Compound - have many blades per leaf

6
Veins in leaves

• Pinnate
• palmate

7
stems

• Support leaves
• and flowers
• Transport water
• and nutrients
• within plant
• May be used for
• storage (potato)

8
Types of stems

1. Herbaceous
2. Shrub
3. Vine
4. tree

9
roots

• Absorb water and minerals
• Anchor plant
• Some store
• food (carrot)

10
Root tip
11
Types of roots

• Fibrous root

• Tap root

12
Flower reproductive organ

• Produces male and female gametes
• Provides
• structure for
• fertilization

13
seeds

• Reproductive structure containing stored food and
  plant embryo

14
Dispersal adaptations

• Wind
• Water
• animals

15
fruit

• Structure containing seeds

16
Plants in the biosphere

• Producers base of the
• food chain.
• Energy in plants is
• transferred to all other
• organisms when the plants
• get eaten

17
Provide oxygen for aerobic organisms
18
Provide shelter for many organisms
19
Human uses

• Agriculture 90 of the food you eat directly or
  indirectly comes from only 20 different kinds of
  cultivated plants
• Rice, corn, wheat, potatoes, etc.

20
Medicines from plants
21
industry
22
Uses of cellulose
23
Fossil fuels
24
Problems caused by plants

• Some are poisonous
• Weeds
• Root damage..

25
Plant cells

• Rigid cell wall of cellulose and other tough
  materials
• Cells are connected to each other by shared
  cytoplasm
• Large central vacuoles

26
Plant tissuestissue group of similar cells
performing the same function

• Dermal protective, covering
• Outermost layer
• Protection includes
• bark in trees
• Some cells contain
• chloroplasts, so they
• perform
• photosynthesis

27

• Vascular tissue transport or conduct materials
  around plant
• Xylem water and
• minerals up
• phloem food down

28
Ground tissue fundamental tissue not
vascular, dermal or meristematic ground tissue

29
Parts of a Flower
carpel
receptacle
30
Pollination transfer of pollen from anther to
carpel

• Self pollination.
• Wind pollination.
• Insect/bird/bat pollination

31
Fertilization

• Occurs after pollination

32
Seeds

embryo

Dicot seed
Monocot seed

embryo

33
Seedling growth
34
Classification of Plants
35
Plant diversity

• Nonvascular plants
• Bryophytes mosses no xylem or phloem

36
Vascular plants xylem and phloem

• Nonseed vascular plants - Ferns reproduce using
  spores

37

• Seed producing vascular plants
• Gymnosperms
• Naked seeds (oh my!)
• Angiosperms-
• flowers

38
Length of life of a plant

• Annual

biennial
perennial
