Question

Mark the odd one out(w.r.t ploidy level)

• A. nucellus
• B. integument
• C. funicle
• D. embryo sac

Answer 1

The correct option is D embryo sac

Considering if the ploidy of plant is 2n, 1)Nucellus(located within the integumentary) have abundance reserve food materials. Its ploidy is 2n.

2) MMC(produces haploid gametophytes by meiotic division) Since, it undergoes meiotic division its ploidy is 2n. The integument and funicle are also diploid in nature.

3)Female gametophytes also called as embryo sac(produced by meiotic division from Megaspore mother cell) has ploidy n.

So the correct option is 'Embryo sac'.
