Vedclass · Answer

(C) During the process of fertilization,when a sperm makes contact with the egg,it triggers the cortical reaction. Cortical granules,which are present just beneath the plasma membrane of the egg,release their contents into the perivitelline space via exocytosis. These granules contain enzymes and acid mucopolysaccharides. The acid mucopolysaccharides absorb water and swell,creating a physical barrier that prevents polyspermy. This modified structure is known as the fertilization membrane.
