Select the INCORRECT statement about Phylum Arthropoda.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Lignin is the main component of the exoskeletons of arthropods.

  • The INCORRECT statement about Phylum Arthropoda is:
  • "Lignin is the main component of the exoskeletons of arthropods."
  • This statement is incorrect because the main component of the exoskeletons of arthropods is chitin, not lignin. Chitin is a complex polysaccharide that provides strength and flexibility to the exoskeletons of arthropods, including insects, crustaceans, and arachnids. Lignin, on the other hand, is a complex organic compound found in the cell walls of plants and is not a major component of arthropod exoskeletons.
