The flower - Coggle Diagram

- - - - For (1) to happen , the flower needs to be bisexual i.e. with both male and femal parts.
      - If flowers are unisexual i.e. either male or female reproductive parts is present, they can still self pollinate. A male can transfer pollen grains to flower on femal flower the same plant.
  - - - tranfer of pollen grains by insects is called insect pollination
        
        eg. mustard, Marigold , Dahlia and salvia
    - - Large anthers on long filament hang outside the flower. The pollen is blownaway by wind pollen stick to feathery stigmas
        
        eg. grass, maize, sugarcane, etc.
    - - Aquatic plant realease pollen grains into water and the water carries pollen grains for pollination.
        
        eg. vallisneria, water weed, pond weed
    - - some of the agents that help for water pollination are birds, bats, etc.
        
        eg. orchids, kapok,baobob , sausage tree, floss-silk
- - - - Stucture
        
        Made up of petals
        
        Large, fragant and brightly coloured
        
        Brightly coloured and sweet smell makes it attractive
        
        attracts insects for pollination
      - function
        
        Pollination
      - Petaloids-Sepals are absent or are fused with the pettals in a flower
      - Second whorl of the flower
    - - Structure
        
        Made up of sepals
        
        tiny leaf-like stucture
        
        usually green in colour

  - - - Fourth and innermost whorl of the flower
      - structure
        
        Made-up of Pistil/Carpel - female reproductive organ
        
        one or many
        
        each pistil or carpel
        
        ovary
        
        swollen part at the base, contains ovules-female gametes
        
        style
        
        tube like stucture, transfers male pollen grains into the ovary
        
        stigma
        
        terminal part

        Made up of stamens-male reproductive organ
        
        one or many
        
        Each stamens consists
        
        Filament-thin,thread like stalk
        
        Anther-two lobed head containing pollen grains
        
        each pollen grain consists of male gametes
      - Function
        
        Reproduction
      - Third whorl of the flower
- - - - epi - above ,geal- soil
        
        the cotyledon grows above the surface of the soil
    - - hypo- below, geal - soil
        
        the cotyledon grows below the surface of the soil
