Polyembryony occurs in plants when:

  • A More than one ovule matures and develops fully within a single ovary chamber simultaneously
  • B Multiple embryos develop in one seed (from zygote, synergids, nucellus cells, or unfertilized egg)
  • C Seeds are released from the mature fruit in tightly clustered groups all at the same time
  • D A single flower develops several largely independent and separate pistils side by side

Correct answer: B. Multiple embryos develop in one seed (from zygote, synergids, nucellus cells, or unfertilized egg)

Explanation: Polyembryony: multiple embryos in one seed. Examples: Citrus seeds. Can arise from additional zygotes, synergid cells, or nucellus cells developing into extra embryos (adventive embryony).

Concept context

Flower structure, pollination, double fertilization, and seed/fruit development — the highest-scoring Class 12 biology chapter in NEET.
