Question

Out of C,H,O and N which elements are taken by plant mainly through the roots from the soil?

Answer 1

Sixteen chemical elements are known to be important to a plant's growth and survival. The sixteen chemical elements are divided into two main groups: non-mineral and mineral.

The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon (C).

The 13 mineral nutrients, which come from the soil, are dissolved in water and absorbed through a plant's roots. They are as given below:

Nitrogen (N), phosphorus (P), and potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S), boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn),

So the answer is 'N'
