how do plants collect water
Need for Water Like all living things, plants need water to survive. Plants use water to maintain their shape, obtain energy through photosynthesis, collect dissolved nutrients from the soil, transfer small molecules throughout the plant, and cool off leaves in hot weather through evaporation. Because they need so much water, plants must have an efficient system to collect it. Roots. Plants obtain water through the soil. The roots are the transportation system to get the water from the soil and to the parts of the plant where it is needed. The roots branch off into smaller and smaller roots, and the smallest roots are called root hairs.
