Life Cycle of Angiosperm Lifeeee (Developmen of flower (Stamen and…

- - - - Located at the growing tips which produce root and shoot tissues.
    - - Initiate leaves during vegetative development.
    - - Give rise to various organs of plants that responsible for growth.
    - - Produce a small leaves before produces floral meristems
    - - Tissue in the most plants containing undifferentiate cell
    - - Give rise to sepals, petals, stamens and carpels.
- - - - White or brightly colour
      - Function is attracting a insect or bird by agency of which pollination
- - - - Carpelate
      - Staminate
- - - - Cotyledons are brought above the ground
    - - Cotyledons remain in soil
  - - - The cotyledons store food and become first leaves
    - - Only have one cotyledons
  - - - Scattered by wind
      - Get stuck in the fur of animals and depand on water
- - - - Microspore
        
        Male gametophyte
        
        Pollen grain
      - Megaspore
        
        Female gametophyte
        
        Ovary
    - - Male gametophyte develop within anther
        
        2 haploid nucleus contain within mature pollen grain
        
        Germ nucleus
        
        Tube nucleus
      - Female gametophyte develop inside ovule contain ovary
        
        8 haploid nuclei cell
  - - - Sporophyte
        
        Produce spore through meiotic
      - Gametophyte
        
        Give rise the haploid gametes
  - - - Develop into fruit
      - One or more ovule attached by placenta to ovary wall
      - Carpel
        
        Style
        
        Ovary
        
        Stigma
      - Ovule develop into seeds
      - Ovule have integuments-outer layer
      - Megasporangium contain sporophyte cell undergo meiosis to produce megaspore
      - Microphyle
      - Integument develop into seed coat
      - Embryo mature, diploid sporophyte tissue
        
        Seed coat
        
        Fruit
    - - Tapetum provide nutrient
      - Inner wall produce by microspore
      - Microsporangia undego meiosis to produce microspores
      - Exine wall produce microspore and tapetum
      - Tube cell nucleus
        
        Guides pollen germination and growth the pollen tube
      - Pollen tube
        
        Generative cell that will divides to produce 2 sperm
- - - - Long-day plants
      - Day-neutral
      - Short-day plants
