The seeds of some plants are dispersed by water. These seeds typically have characteristics different from the seeds of other plants. For example, plants which disperse their seeds by water possess a structure that minimizes their weight and maximizes their surface area. In addition, the floating tissue might take any of several shapes. The cells filled with air might have a spongy structure or the air might be locked in the seed in such a way that gaps among the cells are almost lost, enabling the seed to float. In addition, the cell walls of the floating tissue are structured in such a way as to prevent water from entering. Besides all this, there is an additional interior segment in these plants which protects the embryo that contains all the genetic information about the plant.
Among those seeds carried by water, there are seeds that can remain in the water for about 80 days without being spoiled or germinating owing to their strong structure. The most famous of these are the seeds of the coconut palm tree. The seed of the palm is put into a hard shell for safe transport. In this hard shell, everything that is needed for a long journey, including water, is available. Also, the outer part is covered with a strong fabric that prevents the seed from being damaged by water.
One of the most significant features of a coconut seed is that it has air spaces that make it buoyant and capable of floating on water. Because of these characteristics, the coconut seed can be carried by ocean currents for thousands of kilometers. When it washes ashore, the seed germinates and grows into a coconut palm tree.
It is quite an exceptional situation that the coconut seeds germinate just as they reach the land because, as is known, plant seeds generally germinate as soon as they meet water. Yet, this is not true for coconut plants. With their distinctive structures, plants which disperse their seeds by water are privileged in this respect. If these plants, too, began to germinate as soon as they encountered water, they would have long ago since become extinct. However, by means of their mechanisms suitable to their particular environments, these plants can continue to exist. It is evident that these precise features and design could not have come into being by the methods evolutionists claim.
The amount of reserved nutrition and water in the seeds, the period of their reaching the land, in short all the delicate calculations made for such features have been perfectly determined by Allah, Who is the owner of eternal power and wisdom.
