BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Some minerals are absorbed by the roots passively. However, most of the minerals are absorbed actively by roots since the concentration is higher in the soil than inside the root cells.

Detailed explanation-2: -Roots are present under the soil. They absorb water and minerals from the soil which are used by plants for their growth.

Detailed explanation-3: -Final answer: Roots are the part of plants that absorb water and minerals from the soil.

Detailed explanation-4: -Phosphate (HPO4−) potassium ion (K+), Nitrate (NO3−) mineral can be absorbed by both passive and Active methods.

Detailed explanation-5: -Instead for plant roots to grow into the soil, they must first encounter and absorb nearby nutrients to develop new root tissue. Since roots have no special radar, sonar or other device to detect nutrients around the corner or in deeper soil layers, they instead depend on, essentially, the nutrients coming to them.
