Plants can be Monoecious
Some plants have flowers that are not perfect, they do not have both male and female reproductive parts in the same structure. Instead they produce male flowers that have only stamens or female flowers that have only pistils. Monecious plants have both male and female flowers rather that perfect flowers.
The monoecious corn plant has female flowers that develop on the side of the plant and emerge from the leaf node. As these flowers emerge they are called the shoot and they develop into the familiar ear of corn. These flowers only have pistils. The styles of corn are long and grow up from the ovary and out of the sepals (husks). They are called silks because of their length and delicate nature. When pollen from the tassle flower lands on the stigma at the end of the silk, the pollen tube can grow through the silk to the ovary. Obviously corn pollen is capable of growing a long tube!
