Introduction:
Answer to Problem 1MC
Correct answer:
The cell wall of fungi is primarily made up of chitin. Therefore, option (c) is correct.
Option (c) is given as “chitin”.
Explanation of Solution
Justify reason for the correct statement:
The fungal cell wall is made up of chitin which is a fibrous substance made up of the polysaccharide. It is a
Hence, option (c) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “lignin”.
Lignin which is found in the cell wall of plants is responsible for the rigidity and prevents water absorption. Hence, it is a wrong answer.
Option (b) is given as “cellulose”.
Cellulose is the main component of plant cell wall. Hence, it is a wrong answer.
Option (d) is given as “glucose”
Glucose is the product synthesized in plants during photosynthesis. Hence, it is a wrong answer.
Hence, options (a), (b), and (d) are incorrect.
The fungal cell wall is composed of chitin which is a polysaccharide having repeating units of N-acetylglucosamine molecules.
