PLANTS, 4 GROUPS (PHYLA), eukaryotic, multicellular, autotrophic organisms…

- - - - sporangia (spore capsules) that produce single-celled spores
  - - - gametes
        
        male = pollen
        
        produced by anthera, a part of stamen
        
        female = ovules
        
        surrounded by several protective layers of cells called the integuments; at one hand small hole called the micropyle
        
        inside ovary and stigma
      - pollination
        
        Insect-pollinated
        
        wind pollinated
      - fertilisation
        
        pollen grain grows a tube through the style using enzymes and enters the micropyle
        
        SEED (protected by the fruit, which derives from the transformation of a part of the flower)
        
        RADYCLE (to become first root)
        
        PLUMULE (to become first shoot)
        
        COTYLEDON (food store)
        
        monocotyledons (one seed leave)
        
        dicotyledons (two seed leaves)
        
        SEED COAT (protective layer)
