[0.7 mark]

• A. n, 2n and 3n
• B. 2n and 3n
• C. 3n
• D. 2n

Answer 1

The correct option is D 2n

After fertilisation, ovule is transformed into seed. In due course, the haploid cells in the embryo sac such as antipodals and synergids degenerate. In groundnut, the triploid endosperm is completely consumed before seed maturation. Thus, the mature seed of groundnut has diploid cells (2n) only.
