Question

Which process prevents polyembryony during seed development in angiosperms?

Options

• The ovary wall divides the embryo sac into separate compartments

• The seed coat prevents multiple embryos from forming

• Double fertilization ensures only one zygote and one endosperm develop

• The synergids multiply to occupy space meant for additional embryos

Answer 1

Double fertilization prevents polyembryony (development of multiple embryos) by ensuring that only one male gamete fuses with the egg cell to form a single zygote. Additionally, the formation of the endosperm from the second male gamete and polar nuclei provides nutritive tissue that supports only one embryo's development, maintaining single-embryo seed development.
