Fungi include organisms that are neither plants nor animals. They are the group of eukaryotic organisms that include yeasts, molds, and mushrooms. They are known to be the decomposers of dead organic matter in an ecosystem. Fungi get food by absorbing the nutrients from other organisms. They do not prepare their own food.

Summary Introduction

Introduction:

Fungi include organisms that are neither plants nor animals. They are the group of eukaryotic organisms that include yeasts, molds, and mushrooms. They are known to be the decomposers of dead organic matter in an ecosystem. Fungi get food by absorbing the nutrients from other organisms. They do not prepare their own food.

Expert Solution & Answer

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 polymer of N-acetylglucosamine molecules.

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.

Conclusion

The fungal cell wall is composed of chitin which is a polysaccharide having repeating units of N-acetylglucosamine molecules.
