Structure of Dicotyledonous Seed:
  • The outer and inner integuments of the ovule develop into the seed coat. 
  • There are two cotyledons.
  • Cotyledons are the embryonal leaves as they store food.
  • The outer layer of the seed coat is called testa while the inner layer is called tegmen.
  • The hilum is the scar on the seed coat through which the developing seeds were attached to the fruit.
  • Within the seed coat, embryo is present.
  • Embryo consists of an embryonal axis and cotyledons. 
  • The radicle and plumule are present on the opposite end of the embryonal axis.
  • Food storing tissue called the endosperm is also present. It is formed after triple fusion.
  • It is generally absent in dicot seeds. So, these are called non-endospermic or non-albuminous seeds.
