Question

Concentration of minerals in the soil is usually __________ than the concentration of minerals in the root.

• A. Lower
• B. Higher
• C. Similar
• D. None of these

Answer 1

The correct option is A Lower

Concentration of minerals in the soil is lower than in root. They dissolve in water and move around soil in the solution. Root hair cells are adapted to absorb the water out of soil by osmosis. Root hair cells have carrier molecules on their surface that pick up the minerals and move them into the cell against the concentration gradient.
