Seed Anatomy

  • Seed coat provides protection

  • Aleurone cells = store abundant protein
  • Cotyledon à leaves
  • Epicotyl à shoot
  • Radicle à root

Process: Seed Germination

  1. Imbibition
  • water uptake, softens inner tissues
  • causes swelling and seed coat rupture
  • more water uptake
  1. Gibberelic Acid
  • Arrives at aleurone cells
  • Activates certain genes
  1. Transcriptionà Transportationà Translation à amylase
  2. Amylase accelerates hydrolysis of starch

Seed Coat Affects Germination

  • Strawberries/raspberries need to be consumed
  • Water
    • Common glasswort needs to be pounded by surf
