Embryo Sac as Female Gametophyte — NEET Biology
✅ Asked in NEET 2024Enclosed within the integuments is a mass of cells called the nucellus. Cells of the nucellus have abundant reserve food materials. Located in the nucellus is the embryo sac or female gametophyte. An ovule generally has a single embryo sac formed from a megaspore.
NTA tests whether students understand that the embryo sac is the female gametophyte (not just a structure) and that it develops from a megaspore within the nucellus. The common mistake is confusing the embryo sac with the ovule itself or thinking multiple embryo sacs form per ovule. Remember: one megaspore → one embryo sac (7-celled, 8-nucleate typically) = the actual female gametophyte. This distinction matters because NEET often asks about gametophyte vs. sporophyte generations in flowering plants, and the female side is less intuitive than male (pollen grain). Knowing the exact location (nucellus) and origin (megaspore) helps answer comparative questions on reproductive structures.
