Angiospermae

  1. 1. CLOSE – SEEDED PLANTSANGIOSPERMAE
  2. 2. Angiospermae :• Is group of plants whose seeds are covered with endosperm that it cannot seen from outside
  3. 3. CHARACTERISTICS OF ANGIOSPERMAE
  4. 4. Stems• There are branched and non-branched stems• Several plants have cambial stems (in dicots), and some have no cambium (in monocots)• Has vascular vesssels(pembuluh pengangkut) in several xylem and phloem
  5. 5. Leaf• Most of close-seeded plants have wide leaves, single or plural with various composition• Have various leaf venations, namely pinnate (menyirip), palmate (menjari), and parallel- veined (sejajar).
  6. 6. Flowers• Composed of sterile and fertile petals (sporophyll)• Sterile petals are consisted of calyx and corolla• Fertile petals (sporophyll) are consisted of microsporophyll (stamen) and megasporophyll (pistil)• Stamen is male reproduction organ and pistil is female reproduction organ
  7. 7. DIFFERENCES PLANT’S DICOTS MONOCOTS ORGANSeed Have 2 cotyledons Have 1 cotyledonsRoot Taproot Fibrous rootStem Like a long branched Have same size from cone beginning to the endLeaf Leaf venetation is Leaf venetation is palmate or pinnate parallel-veinedFlower Amount of each part Amount of each part of of flower is multiple of flower is multiple of 2, 4, or 5 three (3)
  8. 8. Female Gamet Formation• Gamet betina dibentuk di dalam bakal biji (ovule) atau kantung lembaga.• Pada bagian itu ada sel induk megaspore (sel induk kantung lembaga) yang diploid.• Membelah secara meiosis terbentuk → 4 sel yang haploid (3 sel mereduksi, 1 sel berkembang).• Membelah secara mitosis 3X (1 sel 2sel 4 sel 8 sel ) terbentuk 8 inti sel haploid.
  9. 9. Next• 3 sel menuju mikrofil/celah bakal biji (2 sel sinergid, 1 sel telur).• 2 sel menjadi kandung lembaga sekunder.• 3 Sel menuju arah yang berlawanan dengan mikrofil → antipoda
  10. 10. Male Gamet Formation• Pembentukan butir serbuk terjadi dalam kantung sari.• Sel induk butir serbuk sari (diploid) membelah secara meiosis→empat sel butir serbuk (haploid).• Masing-masing butir serbuk membelah secara mitosis → satu inti vegetatif dan satu inti generatif.
  11. 11. Next• Serbuk sari yang jatuh di kepala putik terdiri atas satu sel dan dua dinding pembungkus (eksin/selaput luar dan intin/selaput dalam).• Eksin pecah.• Intin membuat pembuluh serbuk sari.• Buluh serbuk tumbuh dan menuju ruang bakal biji.• Inti serbuk sari membelah → satu inti vegetatif (besar, di depan) dan satu inti generatif (kecil, di belakang).• Inti generatif membelah menjadi 2 inti generatif (spermatozoid).
