Detailed explanation-1: -Roots absorb water and minerals and transport them to stems. They also anchor and support a plant, and store food.

Detailed explanation-2: -The roots of plant have two primary functions. Roots anchor the plant firmly to the soil. This enables the plants to stand upright. The other function is to absorb water and minerals from the soil.

Detailed explanation-3: -► Roots anchor the plants in the soil and absorb nutrients and water that are needed by the rest of the plant. ► Stems support the upper part of the plant and act as a transport system for nutrients, water, sugar, and starches.

Detailed explanation-4: -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-5: -root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
