Explanation:

In water, an embryo can exist without desiccation hence remain viable until it is able to develop into another plant. On land, however, the embryo will be prone to desiccation and seeds are a plant’s adaption to survive life on land. The seeds have a pulp that provides the moist environment enclosing the embryo. In addition, seeds have a testa/seed coat that drastically lowers the rate of loss of water from the inside of the seed to the environment.

every el niño cycle is different. every year.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
