उत्तर
Flowers which have single ovule in the ovary and are packed into inflorescence are usually pollinated by wind.
Explanation:
Wind-pollinated flowers frequently have a single ovule in the ovary and are packed in an inflorescence. Pollen, which is lightweight and easily transported to other flowers by the wind, is usually produced in great quantities by these flowers. The crowded arrangement of an inflorescence increases the likelihood of successful wind pollination, and the single ovule guarantees that just one seed will grow following pollination. Grass and certain trees, such as pines, are examples of such plants.
