Question

(a) How does the megaspore mother cell develop into 7-celled, 8 nucleate embryo sac in an angiosperm?
(b) Draw a labeled diagram of a mature embryo sac.

Answer 1

Answer:

Draw a labelled diagram of a mature embryo sac. The megaspore mother cell produces two nuclei by the mitotic division which moves to opposite poles and forms 2- nucleate embryo sac. ... Other 3 are at the chalazal base called as antipodal cells. Thus, the angiosperm embryo sac is 8 nucleated and 7 celled
