Seed Structure

• Seed

  • Testa (outer seed coat that protects the embryonic plant)
  • Micropyle (small pore that allows passage of water)
  • Cotyledon (contains food stores and forms embryonic leaves)
  • Plumule (embryonic shoot)
  • Radicle (embryonic root)
• Seed germination

  1. Seed dispersed from parental plant

  2. Seed germinates

  3. Gives rise to new plant
• When fertilisation occurs, the ovule will develop into a seed (which may be contained within a fruit)
