-As we have learnt:

  • A typical dicotyledonous embryo consists of an embryonal axis and two cotyledons. 
  • The part of embryonal axis above the level of cotyledons is called epicotyl. 
  • It terminates with the stem tip, called plumule (future shoot). 
  • The part below the level of cotyledons is called hypocotyl which terminates in the root tip called radicle (future root). 
  • The root tip is covered with a root cap (calyptra).
  • With the growth of an embryo, the ovule enlarges. Its integuments ultimately become hard to form protective coverings.
  • Now the embryo undergoes rest and the ovule gets transformed into the seed.
