Question

In most of the fungi, cell wall is chiefly made up of
a) Cellulose
b) Chitin
c) Protein
d) Lipid

Answer 1

Hint: Fungus belongs to the kingdom Mycota. Fungi are cosmopolitan and occur in air, water, soil and on animals and plants. The cell wall of fungi is composed of polysaccharides and chitin.

Complete Answer:
- Fungus belongs to a group of eukaryotic organisms that include unicellular and multicellular fungi.
- Cellulose is the major component present in the cell wall of green plants, algae etc which helps plants to stay stiff. It is the main source of fibres in the diet.
- Chitin is a complex carbohydrate that forms the outer shell of insects, fungi, crustaceans, arthropods and some algae.
- Proteins are present in plants to fulfill the needs of components like nitrogen, sulfur and carbon for the development of the plants. They are present in the vegetative cells of the plant.
- Lipids play a vital role in intracellular signaling in plants. They are the important component in cell membrane and provide support in metabolic processes in plants.

Therefore the answer is (b) Chitin.

Note: The cell wall of fungi consists of α- and β-linked glucans, glycoproteins and pigments along with the presence of chitin.
