Question

development of monosporic, biosporic, and tetrasporic embryo sacs. neat and labelled daigram

Answer 1

Monosporic — In this type of development 3 megaspores of tetrad get degenerate one remain functional and forms embryosac.

Bisporic — when two megasporic nuclei takes part in formation of embryosac. Both the nuclei are genetically different.

Tetrasporic — In this type due to failure of cytokinesis I and II a four nucleate coenomegaspore tetrad is formed and all 4 nuclei participate in formation of embryosac.

and for diagram i m sorry because i dont know
