Question

The absorption of ions or minerals from the soil by roots is

Answer 1

The correct answer is mostly by active transport

• In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. 
• In contrast to water, some minerals are actively taken up by plant cells. 
• Mineral nutrient concentration in roots maybe 10,000 times more than in surrounding soil.
