Explanation:
Detailed explanation-1: -Osmosis helps plants to absorb water and minerals from the soil.
Detailed explanation-2: -Water from the soil is absorbed by the roots through a process known as osmosis. The cell membrane of the root hair cells acts as a semi-permeable membrane. The cell sap inside the vacuole is a strong solution with low water concentration.
Detailed explanation-3: -Plants absorb water and minerals from the soil via their roots. The root hairs on roots increase the surface area of roots to facilitate absorption of water and minerals that are dissolved in the soil water. The xylem then conducts the absorbed water and minerals from the roots to the shoot system.
