Vedclass · Answer

(A) The ovum secretes a chemical substance known as $Fertilizin$ (a glycoprotein) from its surface. This substance acts as a chemoattractant that attracts the sperm,which possesses $Antifertilizin$ on its surface. The interaction between $Fertilizin$ and $Antifertilizin$ is a species-specific reaction that facilitates the binding of the sperm to the ovum during the process of fertilization.
