                                An ear of corn can contain hundreds of kernels, and for each one to develop, a single strand of corn silk must first be successfully pollinated. These fine, silky threads on top of corn are not just a nuisance; they are a vital reproductive component of the maize plant, essential for producing those sweet, juicy kernels we enjoy.
