Question

C H And O are is what is To plants​

Answer 1

Answer:

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

Explanation:

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'

Answer 2

Answer:

Carbon (C), hydrogen(H) and oxygen(O) are the macronutrients nutrients plants receive from air and water.

Explanation:

• The first of these macronutrients, carbon (C), is required to form carbohydrates, proteins, nucleic acids, and many other compounds; it is, therefore, present in all macromolecules. On average, the dry weight (excluding water) of a cell is 50 percent carbon, making it a key part of plant biomolecules
• Hydrogen and oxygen are macronutrients that are part of many organic compounds and also form water.
