PLANTS THAT REPRODUCE BY MAKING SEEDS
SEED PLANTS PLANTS THAT REPRODUCE BY MAKING SEEDS
2
SEEDS The reproductive package
3
SEEDS The reproductive package
4
SEEDS The reproductive package
5
SEEDS The reproductive package Three parts to each seed: The Seed Coat The Endosperm The Plant Embryo
7
The Seed Coat Tough outer covering! Resistant to drying out
Can not be digested!
8
THE ENDOSPERM The plants food source
Made through the fertilization process, that’s where it gets its name The largest part of the seed!
9
THE PLANT EMBRYO Three parts to each embryo: Pre Leaves - Epicotyl
Pre Stem - Hypocotyl Pre Root - Radicle
10
THE EMBRYO
11
SEED PART
12
SEED PLANTS Two Major Types ANGIOSPERMS GYMNOSPERMS
13
GYMNOSPERMS Literally means: NAKED SEED Produce seeds on scales
Scales clustered on Cones .
15
Seeds form on these scales
.
17
FERTILIZATION PRODUCES SEED SPORES GROW INTO GAMETOPHYTE INSIDE CONE
TREE IS SPOROPHYTE GYMNOSPERMS Life Cycle CONES PRODUCE SPORES FERTILIZATION PRODUCES SEED SPORES GROW INTO GAMETOPHYTE INSIDE CONE
18
THE ANGIOSPERMS The flowering plants!
19
THE ANGIOSPERMS The flowering plants!
20
THE ANGIOSPERMS The flowering plants!
21
THE ANGIOSPERMS The flowering plants!
24
THE ANGIOSPERMS Flowering plants Flower Structures! MALE PARTS
FEMALE PARTS
25
THE FLOWERS OTHER STRUCTURES
26
TREE IS SPOROPHYTE FLOWERS MAKE SPORES CALLED “POLLEN”
POLLEN STUCK ON PISTIL, GROWS TUBE TO OVARY SEED GROWS FROM SPECIAL FERTILIATION SPERM MOVE DOWN POLLEN TUBE - FERTILIZE
27
Monocotyledenous or Monocots
FLOWERING PLANTS TWO TYPES Monocotyledenous or Monocots and Dicotylenenous or Dicots COMPARING THE TWO
28
QUIZ YOURSELF ON THE SEED PARTS
EPICOTYL HYPOCOTYL RADICLE SEED COAT ENDOSPERM EMBRYONIC PLANT
