Description of embryonic sac
Give a brief description of the term embryonic sac? Which are the cells that form embryonic sac? And also write down their ploidies?
Expert
The embryonic sac is female gametophyte of the angiosperms. The embryonic sac is composed of three cells which remain next to micropyle, two lateral synergids and central oosphere (egg); one binucleated cell, polar nuclei, is placed in central region; three antipodal cells stay in opposite side to micropyle.
Because all of these cells come by the mitosis from functional megaspore they are haploid.
