To determine:
Whether the statement “Animal cells have chitin walls.” is true or false.
Introduction:
Chitin is a chemical compound which is present in the cell walls of the
Answer to Problem 1SQ
Correct answer:
The given statement “Animal cells have chitin walls,” is false.
Explanation of Solution
Chitin is one of the major components of the protective armors of various organism such as spider, beetle, crab, and shrimps. Chitin is not present in the cell wall of the animals. The given statement is false because:
• The cells walls or cell membrane of the animals is made up of proteins, carbohydrates, and lipids. Chitin is present in the cell walls of the fungi and is the main component of the exoskeleton of crustaceans and arthropods.
Therefore, the animal cell does not contain chitin.
