Vedclass · Answer

(B) Root pressure is the positive pressure that develops in the roots of plants due to the active absorption of mineral nutrients from the soil. When nutrients are actively absorbed by root hairs,water follows,increasing the hydrostatic pressure within the xylem. This pressure provides a gentle push,which is sufficient to transport water up to small heights. Root pressure is also responsible for guttation,which is the loss of water in the form of liquid droplets from the vein endings of certain herbaceous plants. While root pressure cannot transport water to the tops of tall trees,it plays a crucial role in re-establishing the continuous chains of water molecules in the xylem that may break under the enormous tensions created by transpiration.
