Question

What is the origin of embryos in Aristolochia according to embryo sac cell types?

Options

• Integument cells

• Endosperm cells

• Synergids

• Antipodal cells

Answer 1

In Aristolochia, embryos develop from synergids, which are specialized cells of the embryo sac located near the micropylar end. This represents a unique example of polyembryony arising from cells other than the egg cell, demonstrating the plasticity of embryonic tissue development.
