Question

process for absorption of minerals by root hair​

Answer 1

❤✌ HEY MATE HERE IS YOUR ANSWER:-

Plants absorb water and minerals salt from the soil with the help of root hairs. They absorb water from the process of osmosis... So the water moves into the root hairs through osmosis. Thus the cell of root hairs become turgid and exert pressure on the adjacent cells.

HOPE THIS HELPS YOU MATE AND PLEASE MARK ME AS BRAINLY AND PLEASE FOLLOW ME ✌❤

Answer 2

Answer:

            * The walls of root hairs are permeable to water and are hydrophilic in nature. They contain vacuoles filled with cell sap.

            * Absorption of water by roots takes place by two mechanism namely, active absorption and passive absorption.

            * During active absorption, the root cells absorb water using metabolic energy released through respi­ration. Active absorption could be either osmotic absorption or non-osmotic absorption.

            * In osmotic absorption, water is absorbed from the soil into the xylem of the roots in the osmotic gradient. In non-osmotic absorption, water is absorbed against the osmotic gradient.

            * In passive absorption, water absorption is due to transpiration. In this, absorption of water into the root is due to conditions originate in the top of the plant and the root cells play a passive role.
