Solution(By Examveda Team)

A specialized membrane called 'trophamnion' is found in Polyembryony type of reproduction.
The meaning of trophamnion is a nutritive sheath that sometimes invests the embryonic portion of the insect egg, especially in polyembryonic insects. It is a giant unicellular provisory structure derived from the second polar body and performs both protective and digestive functions.
Polyembryony refers to the splitting of one sexually produced embryo into many offspring, which are genetically identical to each other but distinct from their parent, thus differing from asexual budding.
