Question

Identify the substance involved in incrustation in plants.

• A. Linulin
• B. Inulin
• C. Lignin
• D. P proteins

Hint:

In crustation processes, minerals typically deposit rather than lignin.

Answer 1

The Correct Option is C

Step 1: Concept
Substances in Plants

Step 2: Meaning
Understanding different substances present in plants and their roles.

Step 3: Analysis
Lignin is a complex organic polymer found in the secondary cell walls of plants, particularly in woody tissues. It provides structural support and contributes to the rigidity of plant cells. Lignin is not directly involved in incrustation but is crucial for plant structure. Incrustation refers to the deposition of mineral substances on the surface of a plant or its parts.

Step 4: Conclusion
Lignin, while important for plant structure, does not play a direct role in the process of incrustation involving mineral deposits. Final Answer: (C)
