Question:
Plants usually absorb Nitrogen in the form of nitrates because Nitrogen is __________
Plants usually absorb Nitrogen in the form of nitrates because Nitrogen is __________
Show Hint
Atmospheric nitrogen is held by a very strong triple bond, so plants cannot use it directly.
Updated On: Nov 13, 2026
- very reactive
- non reactive
- not very essential
- has a strong triple covalent bond
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Nitrogen exists in the air as \(\text{N}\equiv\text{N}\) (dinitrogen).
Step 2: Reason
The triple covalent bond is very strong and needs a large amount of energy to break, so dinitrogen is not usable directly by plants.
Plants therefore take nitrogen in combined forms such as nitrate (\(\text{NO}_3^{-}\)) and ammonium ions.
Step 3: Compare the options
The strong triple covalent bond is given in option (D).
Final Answer:
Nitrogen has a strong triple covalent bond, so plants use nitrates. \[ \boxed{\text{(D) }\text{has a strong triple covalent bond}} \]
