- - - - Self Pollination
      - Cross pollination
        
        Pollen is transferred from one plant to another plant of the same species
      - Insect Pollinated
        
        Stamens within flower so insects must make contact
        
        Stigma enclosed within flower so that insect must make contact
        
        Stigma must be sticky so pollen grains attach from insects
        
        Petals must be large and brightly coloured to attract insects.
        
        Nectaries are present as a reward for insects
        
        Larger pollen grains and sticky to stick to insect bodies.
      - Wind Pollinated
        
        Stamens exposed so wind can blow pollen away
  - - - Anther
      - Filaments
    - - Pistil
        
        Where many carpels (female structures) are fused together
      - Style
        
        The tube that connects the pollen grain with the ovary
      - Ovule
        
        Female gametes are held in this area
      - Ovary
        
        This is where the ovules are kept and protected until it is time to germinate.
      - Stigma
        
        Where the pollen is caught.
  - - - Seed contains a plant embryo and a food store
      - They have a low water content - 5-15% Water so they can stay dormant
      - Food store is in the endosperm or cotyledons
- - - - Oxidation of an energy source
        
        E.g. glucose
    - - Aerobic
        
        Requires Oxygen
      - Anaerobic
        
        Can occur in the absence of oxygen
  - - - Nervous systems
      - Using hormones
        
        Chemical messengers carried in the bloodstream
    - - Changes in patterns of growth
      - Regulated by chemicals
    - - Moving in response to stimuli
        
        Light
        
        Chemicals
  - - - Increasing the volume of cytoplasm
    - - Increases the number of cells in the organism
