Study Notes

Germination and Seed Structure

  • Germination: The process by which a seed begins to grow and develop into a seedling, initiated by the uptake of water and characterized by the breaking of dormancy.

Seed Components and Their Functions

  • Plumule: The bud-like structure in a seed that develops into the shoot system (stem and leaves) of a seedling.
  • Radical: The primary root of a seed that grows downwards and develops into the root system of a seedling.
  • Cotyledons: The first leaves that emerge from a seed, responsible for absorbing light and nutrients for the developing seedling; can be either monocotyledonous (one cotyledon) or dicotyledonous (two cotyledons).
  • Seed Coat: The outer protective layer of a seed, preventing water loss and mechanical damage, and controlling the exchange of gases and water vapor between the seed and the environment.
