Question

In angiosperms, female gametophyte is embryo sac which is formed by (A) Reduction division in megaspore (B) Equational division in megaspore (C) Reduction division followed by equational division in megaspore mother cell (D) Both (B) and (C)

Tardigrade Admin · Accepted Answer

The megaspore mother cell undergoes, reductional division to form four megaspore, three of which degenerates, one functional megaspore undergoes mitosis to form embryo sac or female gametophyte. The functional megaspore undergoes, three mitosis to form seven celled, eight nucleate embryosac.
