In some cases, the fallen fruit is carried by other agents like water, wind, birds or animal and helps in the dispersion of seeds. The longer a seed stays in the air, the farther it can be blown by the wind, helping the plant species widely scatter its offspring. Is a fruit or a seed more likely to be dispersed by the wind? Some seeds, like those of the jacaranda, are flutterers and have papery edges to help them disperse. One fish was caught with 141 seeds in its system! Mention the part of the fruit whose modification helps in this mechanism. Seeds contained within fruits need to be dispersed far from the mother plant, so they may find favorable and less competitive conditions in which to germinate and grow. Coconuts are well known for their ability to float on water to reach the land where they can germinate. An example of data being processed may be a unique identifier stored in a cookie.
