Which is the most common type of embryo sac in angiosperms?

Options

  1. ATetrasporic with one mitotic stage of divisions
  2. BMonosporic with three sequential mitotic divisions
  3. CMonosporic with two sequential mitotic divisions
  4. DBisporic with two sequential mitotic divisions

Correct answer

B. Monosporic with three sequential mitotic divisions

Step-by-step solution

The most common type of female gametophyte (embryo sac) in angiosperms is the monosporic embryo sac in which the embryo sac develops from a single functional megaspore (n) while the other three megasproes degenerate. The functional megaspore undergoes three sequential mitotic divisions and gives rise to 8-nucleate and 7-celled mature embryo sac.
