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(chǎn)生殊為重要，而這些氣流模式在松球的表現(xiàn)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。
