Home World Builders Session Eight Terrestrial Botany Plants on Land Living on land presents many problems for plants. They are no longer supported by water, so they must grow strong stems. They can get dried out if it doesn't rain. There are wider, and more rapid, fluctuations in temperature.
Land plants have to find new ways to reproduce, and they have to deal with wind.
However, there is more sunlight available, and capturing energy is what plants do. On earth, plants proved to be innovative and adaptable. They developed true roots that absorbed water and minerals and anchored them firmly to the ground. They developed vascular structures that distributed water and nutrients to every living cell. They developed energy storage structures such as tubers, bulbs, and the cotyledons of seeds.
