Plant reproduction Biology G6

• Carpel


  the female reproductive part of a flower consisting of the stigma, style, and ovary

  
• Stigma


  The sticky part of the carpel where the pollen grain can stick to.

  
• Style


  The stalk of a flower's carpel, with the ovary at the base and the stigma at the top

  
• Ovary


  Part of the carpel that encloses and protects ovules and seeds as they develop

  
• Ovules


  A structure that develops within the ovary and contains the female gametes. Forms a seed when fertilised by male gamete

  
• Stamen


  The male reproductive part of a flower consisting of the anther and filament.

  
• Filament


  The stem of the stamen; it holds up the anther

  
• Anther


  The part of the stamen that produces the pollen.

  
• Pollen


  The male gamete in plants

  
• Pollination


  the transfer of pollen from an anther to a stigma

  
• Self-pollination


  the transfer of pollen from an anther to the stigma of the same flower or to the stigma of another flower on the same plant

  
• Cross-pollination


  when pollen from one plant is transferred to the stigma of another plant

  
• Pollen tube


  A tube that forms in the style and allows the male gamete to enter the ovule.

  
• Fertilisation


  Fusing of a male gamete with a female gamete.

  
• Seed


  Structure that forms after successful fertilisation of the ovule

  
• Fruit


  A mature ovary of a flower that protects dormant seeds and aids in their dispersal.

  
• Plumule


  the part of a plant embryo that will, when mature, become the leaves

  
• Cotyledon


  Food store inside seed

  
• Radicle


  An embryonic root of a plant

  
• Testa


  Waterproof outer coat of a seed

  
• Germination


  the process whereby seeds sprout and begin to grow

  
• Dormancy


  When a seed does not germinate immediately after leaving the parent plant; it will wait until conditions are ideal

  
• Gamete


  specialized cell involved in sexual reproduction
