Different plants have adaptations to deal with different water regimes. Some are adapted to live in saturated soils where oxygenating roots is a key task while others are adapted to live in desert, where obtaining and saving water is critical.
Work Step by Step
In Fig. 56.2 you can see that different trees prefer different amounts of moisture. Review earlier chapters on the physiology and development of plants to get ideas for the extremes to which plants have adapted.
