Which of the following is a wind pollinated plant?
Some plants like maize, palm, pine, etc. produce dry pollen in large quantities. When these flowers mature, the pollen grains are blown away by the wind, and if they happen to fall on the feathery stigma of the flower of the same type, pollination occurs. Trapa and lotus are examples of plants in which pollination occurs through water. In marigold, pollination occurs through insects.
