For example ， the spiral arrangement of scale - bract complexes on ovule - bearing pine cones ， where the female reproductive organs of conifers are located ， is important to the production of airflow patterns that spiral over the cone ' s surfaces ， thereby passing airborne pollen from one scale to the next 例如，帶有胚珠的松球的鱗苞綜合體的螺旋狀安排，亦即松柏目植物雌性殖器官的所在位置，對于氣流模式的形成與產生殊為重要，而這些氣流模式在松球的表現盤旋上升，從而把在空氣中飛行的花粉從一個鱗苞傳播至下一個鱗苞。
