Changes that occur to the ovule after fertilization

After fertilization ovule changes into seed. With formation of seeds changes also occur in ovary. Its wall is transformed into either dry or fleshy covering around the seed. Such a ripened ovary is called fruit.

After fertilization the zygote divides to form embryo. The fertilized ovule develops into a seed which contain embryo enclosed in a seed coat. As the seed grows the floral parts wither and fall off. Meanwhile the ovary grows in size and ripens to form fruit. The growth of the pollen tube is controlled by the vegetative nucleus.

After fertilization the following changes are occurred;

  • The ovary turns into a fruit.
  • The ovary wall turns into the fruit wall.
  • The ovules turn to seeds.
  • The outer integument forms the testa.
  • The inner integument forms the tegmen.
  • The nucellus in most cases becomes exhausted.
  • The egg forms the embryo
  • The endosperm mother cell turns into an endosperm.
  • The synergids degenerate.
  • the antipodal cells degenerate
  • The micropyle remains as it is.
  • The funiculus turns into the seed stalk.
