Plant roots extract water from

Question

Quizplus · Accepted Answer

Plant roots usually extract water from the unsaturated zone, which is the layer of soil above the water table where the pores contain both air and water. The water in the unsaturated zone is held tightly by the soil particles, and it requires energy for plants to extract it. In contrast, the saturated zone is below the water table and contains water only, which is too deep for most plant roots to reach. Streams can also provide water to plants, but this is not the primary source for most land plants.
