Identify the INCORRECT match regarding the mineral element and its occurrence in living cell.
Mineral element — constituent of
Mineral element — constituent of
Show Hint
Phosphorus is part of membranes, nucleic acids and ATP, not of the plant cell wall.
Updated On: Nov 12, 2026
- Nitrogen — protein
- Phosphorus — cell wall
- Magnesium — chlorophyll
- Calcium — middle lamella of cell wall
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Each mineral element has a particular role as a constituent of cell components.
Step 2: Check the pairs
Nitrogen is a constituent of amino acids and hence proteins, which is correct.
Magnesium is the central atom of the chlorophyll ring, which is correct.
Calcium forms calcium pectate of the middle lamella, which is correct.
Step 3: Find the wrong pair
Phosphorus is a part of phospholipids of membranes, nucleic acids and ATP. The cell wall is made of cellulose, hemicellulose and pectin, so phosphorus with cell wall is the incorrect match.
Final Answer:
Phosphorus with cell wall is the incorrect pair. \[ \boxed{\text{(B) }\text{Phosphorus - cell wall}} \]
