Reproduction, Screenshot 2023-05-28 at 10.22.19 AM - Coggle Diagram

- - - - seeds
      - spores
      - other plant parts
  - - - flowers pollinated
        
        occurs when pollens are transferred from anther to stigma
        
        either birds, insects or the wind help in transfer of pollens
      - ovules fertilised by cell inside pollen
        
        male reproductive cell fuses with egg cell (female reproductive cell)
        
        all flower parts except ovary and ovule withers and drops.
        
        ovule form into seeds
        
        ovary form into fruits
        
        seeds ripen when ovary is ready to release seeds
      - flowers developed into fruits and seeds are dispersed !
        
        seeds must be dispersed
        
        to prevent overcrowding
        
        competition for sunlight, water,space,mineral
        
        dispersed by either...
        
        animals
        
        water
        
        splitting
        
        wind
      - seeds germinate into new plants
        
        roots grow first
        
        to provide support and abosorb water
        
        shoots grows second
        
        seeds can carry out photosynthesis when first leaves of the shoot opens
        
        requires
        
        oxygen
        
        water
        
        warmth
        
        can remain dormant for long until the conditions are favourable
        
        Parts of a Seed
        
        Seed coat
        
        Seed leaves
    - - !
        
        anther
        
        produce pollen
        
        filament
        
        holds anther up
        
        stigma
        
        receives pollen
        
        style
        
        connects stigma to ovary
        
        ovary
        
        protects ovule
        
        forms into fruit after fertilisation
        
        ovule
        
        forms into seed after fertilisation
        
        petal
        
        attract pollinators
        
        stalk
        
        holds flower up to be easily detected by pollinators
      - flower is important in reproduction as it produces seeds
      - mostly have both male and female parts on single flower
        
        morning glory
        
        hibiscus
        
        tomato
      - some has male and female parts on separate flowers
        
        cucumber
        
        watermelon
        
        maize
      - few has male and female flowers on separate plants
        
        asparagus
- - - - produces sperm
    - - transfers sperm into the vagina
  - - - produce egg
    - - location where fertilisation takes place
    - - site where fertilised egg develop
    - - where sperm is deposited
