What role does root pressure play in water movement in plants? -Biology

Description : What role does root pressure play in water movement in plants? -Biology

Last Answer : 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 ... minerals) increases the pressure in the xylem. This pressure pushes the water up to small heights.
