Question

what role does root pressure play in water Movement in plant​

Answer 1

Root pressure is the positive pressure that develops in the roots of plants by the active absorption of nutrients from the soil. When the nutrients are actively absorbed by root hairs, water (along with minerals) increases the pressure in the xylem.

Answer 2

Explanation:

This positive pressure is called root pressure and can be responsible for pushing up water to small heights in the stem. The greatest contribution of root pressure may be to re- establish the continuos chains of water molecules in the xylem which often break under the enormous tensions created by transpiration. Root pressure does not account for the majority of water transport,most plants meet their need by transpiratory pull.
