2. Plant–water relations concern how plants control the hydration of their cells,
including the collection of water from the soil, its transport within the plant and its
loss by evaporation from the leaves.
Flow of water through plant and soil over macroscopic distances is driven by
gradients in hydrostatic pressure.
water is essential for both plants and animals. It serves as a medium for the
dissolution of substances. A huge amount of water is taken up daily by plants and a
considerable amount is lost in transpiration.
Plants need water to grow and maintain their structure. They absorb groundwater,
that is, water collected below ground level due to percolation of rain water, through
their root system. ... Vegetation plays an important role in the water cycle by
preventing soil erosion and increasing groundwater levels
