THE PLANT KINGDOM
Characteristics
Major kinds of plants
Plant Adaptations
THE KINGDOMS OF LIVING THINGS
CHARACTERISTICS OF
PLANTS
 MULTICELLULAR
 EUKARYOTIC
 AUTOTROPHS (chloroplasts)
 MOSTLY ON LAND
 TISSUES AND ORGANS
 ALTERNATION OF
GENERATIONS (2N/1N)
CHARACTERISTICS USED TO
CLASSIFY PLANTS:
• VASCULAR TISSUE – DO THEY HAVE
TUBES FOR CONDUCTING WATER
AND FLUIDS?
• REPRODUCTIVE STRUCTURES:
SEEDS OR SPORES??
NONVASCULAR PLANTS
No vascular
tissue (tubes)
Spores, not
seeds.
Haploid life
cycle
Example: MOSSES (Bryophyta)
SEEDLESS VASCULAR PLANTS
SPORES, NO SEEDS
VASCULAR TISSUE (TUBES)
DIPLOID LIFE CYCLE
Example: FERNS (Pterophyta)
SEEDLESS VASCULAR PLANTS
SPORES, NO
SEEDS
VASCULAR
TISSUE (TUBES)
Example: HORSETAILS
(Sphenophyta)
NONFLOWERING VASCULAR PLANTS
Example: CONIFERS (CONIFERIPHYTA)
VASCULAR TISSUE
SEEDS ON CONES
NO FLOWERS OR
FRUIT
FLOWERING VASCULAR PLANTS
VASCULAR TISSUE
FLOWERS
SEEDS IN FRUITS
Example: ANGIOSPERMS
………………Should they really be called FRUIT PLANTS?
These are not plants. WHY?

Alternation of generations: __________ life cycle.
Alternation of generations: __________ lie cycl
Notice the two stages of the
moss life cycle (dark blue
and light blue). This is the
alternation of generations.
Which stage is the bushy
moss plant we know? 2N or
1N?
Which stage does the moss
spend most of the time in?
2N
or
1N ??????
So, moss are said to have
a____________life cycle.
(haploid or diploid)
