REPRODUCTION - Coggle Diagram

- - - - Make Gametes
      - Assure fertilization takes place
    - - FEMALE (CARPEL)
        
        They can have different positions depending on the flower
        
        Ovary
        
        Style
        
        Ovule
        
        Stigma
      - Petal, Sepal, Nectary, Receptacle, Flower Stalk
      - MALE (STAMEN)
        
        They create pollen
        
        To reach the ovule when the flower "opens"
        
        Filament
        
        Anther
  - - - Insects look for the nectar in the flower and the pollen gets stuck in them
        
        These flowers produced less pollen, and it's spiky and sticky
    - - The wind takes the pollen and it travels around until it meets another flower
        
        These flowers produce more pollen and its smooth and light
    - - Ovule
        
        It's surrounded by a layer called intergumens
        
        Also has a hole in which the pollen has to go through
      - When the pollen meets the ovule fertilization takes place
      - Pollen from the anther drops in the stigma. It starts to grown down a pollen tube that goes thought the style and the ovary, towards the ovule. The male gamete goes down the pollen tube and meets the ovule, they join together and fertilization has happened and a seed is made
      - 4) SEEDS
        
        Zygote divides and creates a embryo that contains
        
        Equivalent to the root and shoot
        
        Plumule
        
        Radicle
        
        Cotyledon- produces food
        
        Parts
        
        Ovary- can grow into a fruit
        
        Tenta- the surface of the seed
        
        Hellium- a little hole, where the seed starts to grow out
        
        All the other parts of the flower slowly decay
        
        It stays dormant
        
        It means that the seed can survive harsh conditions, like cold
        
        5) GERMINATION
        
        Seed absorbs water
        
        That was stored in the cotyledon
        
        It swells, fills up of water and eventually explodes
        
        They dissolve in water

        Cotyledon becomes active

        Once the zygote is formed a seed starts to form too
    - - Pollen arrives to a different kind/species of flower
        
        They can die or
        
        Create a different type of flower
    - - Pollen arrives to the same flower or the same type of flower
- - - - Grow into genetically identical offspring
      - Gamete= Sex cells (Sperm & Egg)
- - - - Once they fuse, the come back to 46 and are called diploid
    - - Fertilization is the fusion of gamete nuclei
        
        Creates a zygote
        
        Grows into a genetically unique offspring
    - - Male
        
        Small and move actively
        
        In humans its the SPERM and in plants the POLLEN GRAINS
      - Female
        
        Large and don't move actively
        
        In humans its the EGG and in plants the OVULE
- - - - That contain genes!
