Plant Reproduction

Plant Reproduction

1. Sexual

   • Flowers
     • produces male cells
       • pollen
         • formed in the anther of the male part
           • stamen
     • female cells
       • egg cells
         • formed in ovary of female part
           • carpel
   • cells join together
     • form seeds

2. Reproduction in Plants

   • Pollination
     • Transfer of pollen from the stamen (anther) of one plant to the carpel (stigma) of another
   • Fertilisation
     • Fusion of male gamete nucleus with the female gamete nucleus to form a zygote
   • Seed and Fruit Formation
   • Seed Dispersal
   • Germination

3. Pollination

   • Insect-pollinated
     • attract insects
       • large, colourful, scented petals
       • nectaries to produce nectar
     • pollen carried on insects
     • stamens/carpels
       • inside
   • Wind-pollinated
     • pollen carried in wind
       • much more pollen
     • stamens/carpels
       • outside

4. Fertilisation

   • occurs after pollen has landed on stigma of the carpel
   • pollen tube grows out of the pollen grain
     • grows down through the style of the carpel
       • tube enters ovary which holds the egg
   • male nucleus passes down through the pollen tube and fuses with the female egg nucleus
     • forms zygote
