Correct Answer: Osmosis


Solution : The correct option is - Osmosis.

Through the mechanism of osmosis, plants are able to take in water and mineral ions from the soil. Water molecules can travel through a membrane that is selectively permeable by a process called osmosis. In this process, water travels from an area of high concentration to an area of low concentration. The cytoplasm of the root hair cell has a lower water potential than soil water.  A huge surface area on root hair cells allows for rapid osmosis and water absorption.
