When all the four megaspores take part in the development of an embryo sac, it refers to:

Find the parts of the embryo sac.

How many of the daughter cells obtained from a megaspore mother cell result in the formation of monosporic embryo sac?

How many of the daughter cells obtained from a megaspore mother cell result in the formation of monosporic embryo sac?

(a ) Trace the development of megaspore mother cell up to the formation of a mature embryo-sac in a flowering plant. (b) Draw a labelled diagram of the structure of mature dicot embryo.

(A) Draw the embryo sac of a flowering plant and label (i) central cell (ii) chalazal end of the embryo sac and (iii ) synergids. (b) Name the cell that develops into the embryo sac and explain how this cell leads to the formation of embryo sac. Also mention the role played by the various cells of the embryo sac .

Megagametogenesis is the process of formation of embryo sac from
