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.The internal water potential of a plant cell is more negative than pure water because of the cytoplasm’s high solute content. Because of this difference in water potential water will move from the soil into a plant’s root cells via the process of osmosis.Get complete view with respect to such significant topic of Biology just follow the Plant Water Relation Mock Test Online Question Answer being dispatched over here
