In angiosperms the correct sequence of events in formation of female gametophyte in the ovule is (A) 3 successive free nuclear divisions in functional megaspores. (B) Degeneration of 3 megaspores. (C) Meiotic division in megaspore mother cell. (D) Migration of 3 nuclei towards each pole. (E) Formation of wall resulting in seven celled embryo sac. Choose the correct answer from the options given below.
  1. $(B),(C),(A),(D),(E)$
  2. $(C),(B),(A),(D),(E)$
  3. $(A),(B),(C),(D),(E)$
  4. $(C), (E), (A), (D), (B)$

Solution

In angiosperms the correct sequence of events in formation of female gametophyte in the ovule is - The megaspore mother cell undergoes meiosis and forms four haploid megaspores.(C) - One remains functional and three degenerate.(B) - 3 successive free nuclear divisions in functional megaspore take place.(A) - Migration of 3 nuclei towards each pole.(D) - Formation of wall resulting in seven celled embryo sac.(E) The correct sequence is $(C),(B),(A),(D),(E)$
