Which of the following statements about minerals absorption in plants is correct?

What essential role does the root endodermis play during mineral absorption in plants?

Method OF mineral absorption | | Translocation OF mineral ion/solute

Mycorrhizae are essential for mineral absorption and mobilisation . They act as :

Mineral Nutrition || Toxicity OF Micronutrients || Mechanism OF Mineral Absorption || Passive Absorption || Active Absorption || Translocation OF Solutes || Soil as Reservoir for Essential Elements || Mobility OF Elements

Assertion :- Most of the mineral absorption by plant is active process. Reason:- Some ions also move in epidermal cells passively.

Identify the correct order 1. Mineral absorption zone. 2. Merictematic zone. 3. Maturation zone. 4. Water absorption zone.

In mineral absorption , (i) There is rapid uptake of ions into free space in its first phase. (ii) Initial uptake of mineral is passive (iii) Entry or exit of ions to and from inner space does not require energy.

Assertion :- Active mineral absorption favours passive absorption of water by roots. Reason:- Active mineral uptake is responsible for creation of water potential gradient In roots.
