Question

The arrangement of the nuclei in a normal embryo sac in the dicot plants is:

• A. 2+4+2
• B. 3+2+3
• C. 2+3+3
• D. 3+3+2

Answer 1

The correct option is B

3+2+3

In a dicot plant, the general arrangement of nuclei in the embryo sac is that 3 nuclei in 3 cells of egg apparatus (one egg and 2 synergids) at micropylar end and 2 polar nuclei in the almost middle region and 3 nuclei in the form of antipodals at the distal end from micropyle, towards nucellus. So total nuclei 3+2+3.
