Every young corn plant will have the male straw-tassels at the top, the male part, and the silk tassels lower of the plant on the developing corn, the female part. The developing corn has ovules in its ears. The pollen from the straw-tassels will pollinate the silk tassels. The silk are the stigma and style of the female flower. When the pollen travels down the style and fertilizes the ovules, a corn(the seed) develops on the cob.
Each silk represents a corn seed. If particular silks are not pollinated, that corn will not be full of corn
