Open in App
Solution
The correct option is B 3+2+3
In a dicot plant, the general arrangement of nuclei in the embryo sac is, 3 nuclei of 3 cells of egg apparatus (one egg cell and 2 synergids) at micropylar end, 2 polar nuclei in the almost middle region and 3 nuclei of antipodal cells at the chalazal end. So, the arrangement of the nuclei in a normal embryo sac in the dicot plants is 3+2+3.
