What to Focus On

  • Fruit is the enlarged ripened ovary.
  • Seed is the ripened ovule and contains the embryo.
  • Grain is a one-seeded fruit with fused fruit wall and seed coat.

  • Monocotyledonous seeds have one cotyledon.
  • Dicotyledonous seeds have two cotyledons.
  • Albuminous seeds retain endosperm.

  • Bean seed is dicotyledonous and exalbuminous.
  • Testa is the outermost hard protective layer.
  • Tegmen is the thin inner protective layer.

Common Mistakes to Avoid

A grain is the same as a true seed.

Testa is the inner seed coat layer and tegmen is the outer layer.

Plumule forms the root and radicle forms the shoot.
