  • 1. LET’S LEARN TO BIOLOGY SLOWLY BUT BEFORE WE STUDY BIOLOGY LET’S A SING ASEREJE OKE…..
  • 2. Are you like it ? I am sure you like it . So let us identify of Spermatophyta. Oh…it is very nice are you very like it.?
  • 3. Chapter Plants with Seeds(Spermatophyta)
    • DESCRIBE
    • They are called kormophyta.
    • They are called anthophyta.
    • They are called tracheophyta.
    • They have seed and fruit.
    • They are called autotrof.
    • They have pigmen.
    • They have two different spore sizes : megaspore and microspore.
    • Megaspores will produce megagametophyte and microspores will produce microgametophyte.
  • 4. Clasification of spermatophyta
    • Spermatopyta are devided become two division :
    • 1. Gymnosperm
    • Identify a characteristic of gymnosperm :
    • - their seeds on the surface
    • - they have two gemetophyt ; male and female gametophyt.
    • -
  • 5. DESCRIBE OF CONIFER .
    • Did you know that the world’s tallest,largest, and oldest trees all belong to a group of seed-bearing plants called conifer? Where is that ? How long does it ?
    • Answer : in california. And it has 112 meters.
    • Four of the division, collectively known as gymnosperm, consist of plants that bear their seeds on the surfaces of reproductive structures called `scale.
  • 6. Clacification of Gymnosperms
    • Conifers
    • Cycads
    • Ginkgoes
    • Gnetophyt
    • I hope you can find it. Where ……
  • 7. Pigure of conifer How long does it ? Guess, please….
  • 8. CONIFERS Describe :
    • Conifers, which make up the division Coniferophyta or they are called evergreens .
    • The members of this class include some of the most important of all land plants .
    • Forest conifers cover areas of Nort America, China, Europe, and Australia.
  • 9. Describe of cycads
    • CYCADS
    • Cycads, which are members of the division Cycadophyta. They are appears more than 225 million years ago.
    • Cycads especially common in the forests.
    • The Cycads plants are still common in tropical regions of mexico, australia, west indies, and florida.
  • 10. GINKGOES
    • These plants were common in fossils that are dated to be more than 200 million years old.
    • Remarkable trees that make up the division Ginkgophyta.
    • The only living species in this class is Ginkgo biloba.
  • 11. Pigure of Ginkgo biloba
  • 12. GNETOPHYTES
    • GNETOPHYTES MEMBERS OF THE DIVISION Gnetophyta.
    • The plants with many characteristic that remind scientist of flowering plants.
    • They have two gametophyte flowers ; male flowers and female flowers
    • Example : Gnetum gnemon
  • 13. SECTION ANGIOSPERMS
    • DESCRIBE THE MAIN CHARACTERISTICS OF ANGIOSPERMS.
    • They are the largest group of plants.
    • The seeds of angiosperm are covered by fruit.
    • ANGIOSPERMS PRODUCE SEEDS ENCASE IN A PROTECTIVE TISSUE OF THE SPOROPHYTE AS THE OVARY.
    • THEY HAVE A FRUITS, THE FRUIT IS COMBINATION OF SEED AND OVARY
    • THEY HAVE A FLOWER SO THEY ARE CALLED “
    • FLOWERING PLANTS ”.
    • . THE FLOWER IS USED REPRODUCTION METHOD.
  • 14. Angiosperm are divided into two classes.
    • Dicots
    • - woody or herbaceous
    • -flowers parts in multiples of four or five.
    • -vascular tissue in the stem forms ring.
    • - two cotyledons
    • Monocots
    • - herbaceous
    • -flower parts in multiple of three
    • -bundles of vascular tissue are scattered throughout the stem.
    • One cotyledon
  • 15. CHAPTER FLOWER
    • IDENTIFY OF FLOWER
    • FLOWERS ARE THE REPRUDUCTIVE ORGANS OF ANGIOSPERMS.
    • THE FOWERS HAVE MANY SIZES AND TYPES.
    • THE FLOWERS ARE FORMED FROM FOUR TYPES OF SPESIALIZED LEAVES: SEPALS , PETALS , STAMEN , AND CARPELS.
  • 16. DESCRIBE
    • SEPALS
    • THEY HAVEGREEN COLOUR DURING THE LIFE OF THE FLOWER.
    • THEY ENCLOSE AND PROTECT THE DEVELOPING FLOWER BUD AND OPEN AS THE FLOWER BLOOMS.
    • PETALS
    • THEY ARE BRIGHTLY COLORED
    • THE FUNCTION OF PETALS IS SERVE TO ATTRACT INSECT AND OTHER ANIMALS.
    • SEPALS AND PETALS ARE CALLED STERILE LEAVES.

      • Merupakan organ tambahan hasil modifikasi batang
      • Berfungsi sebagai tempat penyimpanan makanan dan alat reproduksi (biji)
      • Struktur buah: (1) kulit luar/eksokarpium  lapisan tipis dan kaku, (2) kulit tengah / mesokarpium  berdaging atau berserabut dan (3) kulit dalam (endokarpium)  mengandung biji (Kulit biji, embrio lembaga atau endosperm)
