7 Celled 8 Nucleate Structure Ovule With Labelled Diagram
Process Of Megasporogenesis In Angiosperm In the previous blog, we had talked about how Archesporial cell meiotically divides and form four haploid cell arranged in a linear manner. Now out of the four cells, only one is functional while the other three degenerate. This is known as monosporic development. One functional megaspore will give rise to the female gametophyte . Now let's go in more detail. The functional megaspore will now start to divide mitotically and form two nuclei which start to move in the opposite direction where they form two nucleate embryo sac. Now the resulted two nuclei again divide by mitotic division and in this way, there is a formation of four nucleate and on further it divides more to becomes 8 nucleate of the embryo sac. These 8 nucleate cells arranged in so well manner to form female gametophyte. Out of the eight nuclei, six nuclei co...
