Question

Synergids are

• A. Hexaploid
• B. Haploid
• C. Diploid
• D. Triploid

Answer 1

The correct option is B Haploid

• During megasporogenesis, the diploid megaspore mother cell undergoes meiosis to form four haploid megaspores.
• Out of these four megaspores, three degenerate and one remains functional. The functional megaspore then undergoes mitosis to form 2 daughter nuclei which further undergo two more mitotic divisions resulting in 8 nuclei, 3 of which get organized into egg apparatus comprising of an egg cell and two synergids at the micropylar end, other 3 nuclei get organized into antipodal cells at the chalazal end and the rest 2 nuclei from the central cell.
• Since these 8 nuclei are derived from the mitotic divisions of the haploid megaspore, these are haploid and thus, the synergids are haploid cells.
  

So, the correct answer is B.
