plant reproduction

• pollination

  transfer of pollen grains from the make anther of a flower to the female stigma, leading to fertillisation and seeds
• self-pollination

  transfer of pollen from anther of a flower to the stigma of the same flower
• pollinator

  an insect or other agent that delivers pollen to a plant and so allows fertilisation
• fertilisation

  male and female sex cells fuse together
• fertilisation process:

  • pollen grain and ovule fuse
  • forms a zygote
  • zygote divides
  • forms an embryo
• seed coat; protects the seed from:

  • damage
  • disease
  • insects
  • drying out
• cotyledon

  stores food in form of starch that embryo uses to grow
• germination

  when a seed starts to grow
• seed dispersal: to avoid competition for light, water, nutrients and space

  • animal faeces
  • explosion
  • animal fur
  • water
  • wind
