How can we say that embryo sac is haploid?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The embryo sac is demonstrably haploid because:
- A diploid megaspore mother cell in the nucellus undergoes meiosis
- This produces four haploid megaspores
- Three degenerate; one functional megaspore undergoes mitotic divisions
- This forms the seven-celled, eight-nucleate female gametophyte (embryo sac), all cells being haploid
